Do not miss the patent train!

260 PATENTES FOTO pAfter a two-month break we resumed our modest articles to discuss matters always about science, technology and patents.

Patents do not have to be a milestone that only forms part of the life of Edison, Tesla or Bell. If we believe that we have not invented anything worthwhile, we can think other way, that patents protect the solution to a problem. So, if the word “invention” sounds presumptuous to us, but we solved a technological problem, let`s protect the “solution to the problem” we have found. This, and nothing else, is a patent.

The subject that inspired our today’s article was a poster that is currently hanging in the central courtyard of the National Council for Scientific Research (Consejo Superior de Investigaciones Científicas), where one can read, as you can see in the picture accompanying this article, that the Council for Scientific Research has licensed more than 260 patents in recent years.

And putting them all in a bunch – and we must not forget that the number corresponds to the last 5 years – is, maybe, what we need to find a glimmer of hope and motivation to break the deadlock that research and technology protection are  undergoing in Spain. While, it is true that our universities lack resources and are financially in a very difficult situation; while it is true that companies in need of making savings, will first make cuts in industrial property protection, it is also true that there is an important lack of “patent culture” in general and in all activity areas. These issues mean at least half of the reasons why very few patents are requested in Spain.

Many professionals approach patents with indifference. Actually one can “live without patents” many years, but there comes a day they receive a letter announcing a claim for alleged violation of a competitor’s right. There begins a long journey of stress and worry for which they were not prepared.

Other professionals are highly competent in their field, but flee patents because patents deviate them from – so they believe – his noble task of research, and see no long-term benefit in “wasting time” writing an impossible document and spending money from their research projects, or their company, for a piece of paper that will be kept in a drawer.

In other cases, a company, a research institution, achieves a major breakthrough in a technology area, but they publish with the most naive and childlike joy. “With a little bit of luck” someone cares about that finding. At that point they realize how things could have gone, but did not because, alas, it is too late!.

 All of these situations would be very different if patents were more seriously taken  in our country. Being aware of existing patents serves to not be suddenly scared of  having our flagship product off the market. It also will prevent us to spend much more money than we would have spent on a regular patent surveillance. What are our colleagues doing?, this is not gossip, is just a question of survival.

No, patents are not left in a drawer in the XXI century. As soon they are published, they travel around the world and sometimes they find open doors and are received with enthusiasm. The benefit can be very rewarding for our working environment and our research projects, for our motivation and generation of new ideas.

Nor should we be too modest about our achievements. What we have achieved in our R & D department, or our laboratory in a small Spanish university without a brilliant past, some of them with almost no past, can put us in the story, and on the map. Let’s not miss opportunities, our inventions are as good as those from other citizens of this planet.

Before finishing we just want to ask the readers of this article to include patents in their life, because the working time they add to their day to day will be more than rewarded with a good protection strategy for their “solution to problems” and a good professional advice. Good luck!

The patent attorneys are lifelong learners

20039132-imagen-de-un-libro-con-las-paginas-de-inflexion-en-el-esquema-de-color-sepia-podria-ser-util-para-laThis week, September 9th,  an educational event organized  by the European Patent Institute (EPI) took place in  Barcelona.

People from different countries, mainly from Spain, attended the lectures about the opposition and appeal procedures before the European Patent Office.

You may think that you are familiar enough with the practice of the Opposition Divisions and Boards of Appeal,  but you must not relax. You can feel comfortable with all the rules and details involved, but  a modification of a specific point in the Guidelines, a new case of the Enlarged Boards of Appeal, a new Decision of the President will make you to stay alert.

Therefore, it is great to have these opportunities to take a break and spend one day listening to experts and returning to the office with fresh knowledge and even material to look at when you have to cope with the next opposition case somebody drops on your desk.

It is interesting to listen some tips about how to file a “decent” opposition when the client places an order the day before the deadline. What is more important: filing grounds of opposition without good arguments and/or documents, or filing documents first?.

It is important to find out about the pending cases before the Enlarged Boards of Appeal that could give rise to decisions  diverging from the Guildelines and establishing new case law.

On the way home you make the decision of dedicating at least one hour a week – it is not much – updating your knowledge, and several weeks later you realize how difficult is to keep your word. We are so busy that we are looking forward to spending a day again as when we were students, we are lifelong learners!.

Back from holidays with patent related news

ciruelasMany people in Spain are returning home and back to work again after the holidays. Some have even suggested that the actual beginning of the year is September 1st or more precisely, the day when the school year starts in our country.

During this summer some patent related events took place: for example, the President of the European Patent Office (EPO) travelled to the Netherlands to lay the foundation stone for the new building of this organism in that country. These facilities will provide working places for 1750 persons. Not bad at all!. This means that patents play a relevant role in the economy of many countries, and that the EPO continues to be a major player among the European Organisations.

Another interesting event took place in Santander where the President of the European Patent Office also travelled to discuss and promote the collaboration of the EPO and Spain with the Latin American countries in patent related matters. One of the goals is to improve access to and the public dissemination of Latin American patent information. Even if it sounds a bit pessimistic, it has to be said that in Latin America, as it happens in Spain, a first essential thing to achieve is to have a high number of patents, at all, to spread.

In order to finish our today comments with a piece of good news, we can tell that back from holidays we are glad to see that there are several positions as patent examiner at the Spanish Patent Office to be ocupied by future patent experts – because these persons are not (most probably) patent experts yet – . These are not as many as we would like them to be, but at least five persons will have a job in the near future. We wonder whether these vacancies are the consequence of the retirement of former workers or whether they are the consequence of an increasing working load of the patent examination department. The second option seems to be less probable, at least judging by the number of new national patent applications filed so far this year.

In any case, it is good news  and, who knows?, a hint of the recovery of the Spanish economy?.

In the world of patent searches: approaching STN

imagen post 4 agosto 2014We can say that Germany, US and Japan came together to produce one of the most powerful tools for state of the art searching. STN is operated jointly by FIZ-Karlsruhe, by CAS in North America, and by the Japan Association for International Chemical Information (JAICI) in Tokyo.

We shall not go through the list of databases, technology areas and disciplines that STN covers. Let say that you can find everything, and in particular regarding patents, chemical information, including structure searches, pharmaceutical information, biosequences and toxicology.

Just to remember: it seems that no one knows which are the actual sources of this piece of information but you find it everywhere, and in the brochures of the STN web site too: “about 80% of the technical information disclosed through patent literature is not found anywhere else”. Therefore, you should consider this fact when you need to search state of the art.

If you want to search in patent databases among the so-called “first-level data bases” or the ones called “added-value data bases”, you have both at STN. Added-value data bases include specific abstract, indexes, classifications etc, prepared by a staff of experts, whereas first-level databases include full text and are more quickly updated.

Through STN you have access to Derwent World Patent Index, an added-value database with more than 20 million documents back to 1963 and updated every 3 to 4 days (we talked about it in previous articles), to INPADOC (the worldwide legal status database, also mentioned in our article of March 31st), to CAplus (a collection of records corresponding to patent inventions in the chemical arts; these records consist of re-written abstracts and special indexing content created by skilled persons) or the INPAFAM (a bibliographic patent family database, covering the full spectrum of patent technologies for 95 issuing authorities, dating from the early 1800s). In other words, you can have access to the best patent databases in the world.

Another piece of information to remember: Europe spends billions of euros every year in “researching” and “inventing” things that were already “researched, invented, and published”. According to the European Patent Office up to 30% of all expenditure in R&D is wasted on redeveloping existing inventions. This is another reason to make a meaningful search before starting a research project or before initiating a patenting procedure.

You can access STN in different ways and depending on the products you want to focus on, such as: STN Express – that offers access to STN’s complete portfolio of more than 180 scientific and technical databases, STN on the WebSTN Easy, STN AnaVisT or STN Viewer. For any of them you will need an STN account and Login ID. You will need to at least take a look at the brochure “STN® Access Guide”.

You also will be able to order STN to make searches for you, as single searches or on a subscription basis. There is a SDI Service (Selective Dissemination of Information Service) available, and an SDI profile can be set up after a search has been carried out. The search frequency (e.g., weekly, biweekly, or monthly) is to be chosen by the customer. The cost of the SDI Service depends on the complexity of the search query and the time and expenses incurred for initiating, checking, modifying, and deleting the search query as required by the customer.

Regarding prices, you can consult the “Price list search service” at the STN web site or even better, just contact them!. Everyone has experienced it at least once! –it is sometimes better to look for information using Google than the web site of the company providing the specific article or service you are interested in. This also seems to happen with STN. You “ask” google about the prices of STN and the company Intellogist comes to your aid: “A large reason why STN is not used as a primary search tool by many searchers is its relatively high cost. Often times, every time a term is searched or an answer is displayed, the user incurs a fee. This fact results in STN often being used only when other (less expensive) search tools have failed or are inadequate for a particular search.” You can also read at Intellogist the following: “users often adopt a strategy of “get in and get out”: sign on to STN, conduct the search quickly (or import a search strategy), save the results, and sign off. This type of strategy is designed to minimize costs while still providing quality results”.

After these hints on STN, we wish you all the best if you decide to have your own STN experience.

Enjoying science in Andalusia

20140628_145413This will be the last interruption of our articles about the searching of state of the art. We have to make this break for telling you about the Park of Science of Granada and inviting everyone to visit it.

This is one of the best museums of science I ever visited, and I am happy to say this, especially when research and science are not particularly blessed by the politiciens in our country, independently on the fact that they try to make us to believe the opposite.

I have been several times at the Palais de la Découverte in Paris, which is really wonderful. I have visited science museums in London, Amsterdam, Madrid or New York. Also our Ciudad de las Artes y la Ciencias in Valencia is worth visiting, although I wonder if it is well preserved.

This weekend I was surprised and delighted to see how enjoyable and well designed is the “Parque de las Ciencias” of Granada. If you go there, Albert Einstein welcome you sitting at the entrance and you start your visit having a pleasant conversation in the language of your choice with a couple of robots. We had the opportunity to listen to live music performed by students  from the Conservatory. As in other museums, there are many workshops and exhibitions  devoted to particular subjects. We were for example listening interesting explanations about the research on algae, carried out at Spanish universities as the ones of Malaga or Granada, and it was even more interesting seeing small children listening quietly to the explanations  including definitions of pH, absorbancy or photosynthesis, and watching at the experiments without batting an eye.

You can wander around the buildings and learn about plants, observing them and reading the pieces of information  very carefully placed under wooden layers to protect the plastic sheets from the weather and to increase your curiosity. You can visit and have fun inside the tropical forest wherein monarch and zebra butterflies among others, pass in front of you almost rubbing your face.

The room devoted to the human body is huge and amazing, even scaring, when you see a human heart, a real one, just especially treated to lie there as long as wanted. The amount of information accompanying each object, sample or model is perfect, not too short that you do not learn something, not too long so that people do not finish to read it. Also the language is appropriate for the  purpose of a museum, that is to spread knowledge and maybe, hopefully, to awake interest for science, literature, or history…. Some patents could be filed in the future as the result of a visit to this wonderful place.

If you are tired of biology or physics, just visit the rooms about the Andalusian and Spanish history and enjoy the magnificent exhibitions including manuscripts, scrolls, models, maps and small treasures of the interesting mixture of such different cultures.

Of course, you do not need to go outside to have lunch and read newspapers. You can do both in the nice available rooms, or at the tables near the gardens. No excuse if you have children because you can spend time in the “garret of the museum” or in playgrounds with slides or a Möbius strip big enough to climb it. Marie Curie can take care of the children while she is standing there holding some laboratory flasks.

20140628_145937If you are planning to visit Granada which is a wonderful city, just save enough time to spend several hours at the Parque de las Ciencias. We thank all the people involved in the splendid task of making a dream to come true. Welcome to the Andalusian museums!.

Premio Príncipe de Asturias de las Ciencias 2014, ¡Profesor Corma!

zeolita jpgSi estáis alguno esperando por el siguiente artículo sobre STN, o Questel, prometemos que aparecerá pronto en esta sección. Pero esta semana tenemos que “aprovecharnos” del buen nombre del Profesor Corma a la vez que le felicitamos desde nuestra modesta posición de “patentólogos”.

Y digo bien, “aprovecharnos”, porque también estamos orgullosos de haber tramitado algunas de sus patentes, y hay que decir que siempre ha sido un placer “molestarle” para preguntarle si la zeolita ITQ-32 podría ser preparada con algún otro elemento, o si tenían más ejemplos a mano para convencer al examinador estadounidense, en su obstinada afirmación de que “the inventor was not in possession of the invention”. Y le prometo, Sr. Examinador, que en este caso el inventor sí estaba en posesión de la invención, de esa invención y de muchas otras…

Invenciones todas ellas que nos facilitan la vida, que cuidan el aire que respiramos, que ayudan a que nuestras medicinas produzcan el efecto deseado de la mejor manera. Todo esto es parte de la gran contribución al “estado de la técnica” como decimos los de las patentes, de una persona, que con ayuda de sus colaboradores, y dando ejemplo desde la mayor discreción comienza bien temprano cada mañana a pensar en una solución para el siguiente problema, una solución que lo será también para los que ignoran esta actividad silenciosa, para amigos y para desconocidos, para los que a esa hora aún no se han levantado.

Hoy sí le voy a llamar muy alto “Profesor Corma”, aunque durante esas conversaciones sobre zeolitas ITQ y procedimientos de oxidación de alquenos, decía que le llamara Avelino.

Esto es un ¡bravo! para la ciencia española, que se pone un puntito más arriba, pero sobre todo hay que decir ¡bravo, bravo por Avelino Corma! Y también ¡Gracias!.

We are not done with the searching of patents!

bosque nuevo

Upon the break to comment on the draft of a new Spanish Patent Law, we continue our review of the searching tools, in this article the platform ProQuest Dialog. ProQuest Dialog was launched in August 2010 and is the continuation of the 40-year old “Dialog”. PRO stands for Predictable Research Online.

The amount of documents we can search and find with ProQuest Dialog is hard to imagine. To get a very rough idea we can click on “ProQuest Dialog ProSheets” in the left menu of the link: and we find in alphabetical order more than 150 databases!! of the most diverse content. A number of these databases may not be very known, but they do not lack interest. It depends on our searching topic. As an example we are randomly listing a few of them to give an idea of the diversity thereof:

– Biochemistry Abstracts
– Computer and Information Systems Abstracts
– Earthquake Engineering Abstracts
– Human Genome Abstracts
– Pollution Abstracts
– Transport Research International Documentation (TRID)
– TULSA (Petroleum Abstracts)
– UBM Computer Full Text
– Virology & Aids Abstracts
– Water Resources Abstracts
– Zoological Record Plus

For some of them you cannot even guess from their name what their content is about, see a few examples below:

ADIS Reaction Database: has a coverage that includes more than 2000 medical and biomedical journals, and in particular related to adverse drug reactions.

AQUALINE: this is a database with a coverage of more than 6000 serials related to health and safety sciences, oceanic abstracts, and devoted to topics like agricultural biotechnology. It is monthly updated and the coverage started in 1960.

EMBASE (Excerpta Medica dataBASE) it is a database produced by Elsevier and contains over 25 million records from 1947 to the present, related to adverse effects of drugs, anatomy, pathology and other medical matters.

ICONDA: – International Construction Database: it is published by Fraunhofer Information Center for Regional Planning and Building Construction (IRB), and has a coverage from 1976 to present. It covers worldwide technical literature on all fields of building construction, civil and construction engineering, and architecture and town planning. ICONDA contains references taken from sources in more than 20 different countries. It includes periodicals, books, research reports, conference proceedings, business reports, theses, and non-conventional literature that is normally outside the public domain.

And ProQuest Dialog also offers patent literature, which includes databases like:

– Derwent World Patents Index
– Global Patents / LNU (Fulltext and Bibliographic)
– IFI CLAIMS US Patents and Legal Status
– IMS Patent Focus
– INPADOC/Family and Legal Status
– Japan Patents Fulltext
– JAPIO – Patent Abstracts of Japan
– LitAlert
– United States Patents Fulltext

We are more or less familiar with Derwent World Patent Index and INPADOC. No need to further explanation on these two, but what about Global Patents, or LITalert, for example?. Let’s see what we are talking about!:

Only the amount of documents included in Global Patents is absolutely incredible!. We remind you that Derwent World Patent Index includes patents from Soviet Union starting in 1963. ProQuest Dialog through Global Patents offers information from Soviet Union patents since 1900!, or full text patents from Spain since 1827!. This could even go beyond the database of the Spanish Patent Office itself.

The best way to start a self-training course on ProQuest Dialog is to contact:

You can see at a glance where you have to click on (pricing, database content, training etc) in order to get the information you need and how to classify and use it. There is a specific link called “How do I?” that leads you to a complete guide about how to carry out a search using ProQuest Dialog with all the imaginable details and screen layouts absolutely helpful and clear. Of course, we cannot expect to learn everything in thirty minutes. We shall rather need a couple of hours!.

With regard to pricing there are three options depending on the intended frequency of use: a first option with a pay-as-you-go-basis (Standard Transactional Plan) a second option for a “up to a certain number of searches” per year (Commitment Plan), and the last one which does not have frequency or access limit (it is your choice) and is annually paid (Choice and Site License Plans). Through the web site you cannot see any approximate figure for any of them. Therefore we cannot inform you on every “tiny” detail and this is our contribution for now. Have a nice week and nice search time!

Spanish patents for the XXI century

thumbWe have to make a break in our discussion on patent databases and search tools for briefly commenting on the draft bill for the establishment of a new Spanish Patent Law. It was approved by the Council of Ministers two days ago. According to the media, it will help in accelerating the granting of patents. However, we do not think that this will be the most important aspect thereof. In the (first) draft bill published in October 2013  several paragraphs illustrate the grounds for the new law (link: below:

( .

 You may remember as a joke that a patent on the wheel as a “circular transportation facilitation device” was granted in Australia in 2001!, also unbelievable for a developed country. This story could just as well have happened in Spain. Therefore, maybe, one, if not the, most interesting aspect is that, finally, no one will have a patent granted in Spain for the steam engine. Because, until now, it was still possible!, just because the substantive examination was not compulsory and no matter how bad the state of the art report could be, the applicant was not obliged to amend the claims to have novel and inventive claims. Naturally, the application proceeded to grant and to invalidate the “junk” patent you had to file a suit before the court. As patent attorneys, we understand those clients that came to our office to entrust us with the filing of an application for the protection of the distillation procedure. As long as the patent was in force, it had the effect of a perfectly valid one. From now on (not yet, though!) the trick “I just want to have an application number to put the words “patent pending” on my product” will no longer work.

The pride of the Spanish citizens about our country being number nine in scientific publications did not fit with our current patent system, or with the number of patent applications of Spanish origin, or with the fact that Spain is a PCT Examining Authority since 2008.

A really sad reality is that for the last fourteen years in which the substantive examination has been optional, about 90 % (data from the Spanish Patent Office – SPO)) of the Spanish patents have been granted following the so called “general procedure”, in other words, without examination. This means that maybe someone still has to fight against the “wheel patent” within the next twenty years.

Other amendments in the new law will be related to the increase of the legal security and / or the adaptation to the European Patent Convention 2000 (EPC 2000) and the Patent Law Treaty. It was about the time to do this!. For example a post-grant opposition procedure will be established. The possibility of amending the claims during a legal procedure before the court will also be a main change.

Ninety pages of the document entitled “Draft Bill for a new Patent Law” (first draft, October 2013, second draft in December 2013) are to be carefully read. Surprisingly, apparently you cannot find said document through the web site of the SPO, or the Ministry of Industry, Energy and Tourism, but through web pages of industrial property firms and different associations like the AIPPI.

Welcome to the XXI century!

Patents, patents, more patents!. Delphion.

lbreriaWe devoted our previous article on patent and scientific / technological databases to Thompson Reuters (more specifically Derwent and WOK). Just a final comment on Derwent: If we want to make a real single Derwent search we must, before searching the full Derwent collection, submit a billing activation form, agreeing to the terms of use and see the information on pricing.

A meaningful search in Derwent could be made in the Derwent Innovation Index, so that we simultaneously search patent and scientific literature.

We would like to take a new step in our journey through patent database collections. Let’s focus our attention on Delphion today. What you will read below can be found at the Delphion web site, but of course, not at a glance!

Delphion was originally an IBM database, but it is nowadays handled by Thompson Reuters. It contains exclusively patent literature. We can find therein information – and “information” herein does not mean the fulltext and images in all the cases – on:            – United States applications and  patents since 1790,                                                           – German applications and patents since 1968,                                                                     – European applications since 1979 and European patents since 1980,                          – abstracts of Japanese patents since October 1976,                                                           – PCT applications since 1990                                                                                                    – Swiss patents since 1978 and                                                                                                 – INPADOC information. INPADOC is a database created and maintained by the European Patent Office that contains patent family documents from 71 world patent signatories and legal status information from 42 patent offices.  It is publicly available.

A basic suscription to DELPHION costs  US $ 181 a month (Delphion Premier), and the most complete suscription costs US $ 361  a month (Delphion Unlimited).

One cannot say that it is cheap taking into account that we can consult INPADOC for free (which includes information on patents from the former German Democratic Republic for example since at least 1950, as we shall see if a future article), as well as the United States Patent Office web site for the search of US patents and applications, and similarly visit other national patent office web sites for national patents. This is worth considering when taking into account that the countries mentioned above are countries with a web site that allows to effect the same search as through Delphion (in any case, no patents available from Uruguay, for example, previous to year 2000, which also count as state of the art documents!). From this point of view, and also, bearing in mind that  a search is never perfect, one can have doubts about Delphion being the most recomendable data collection for effective searches. Of course, the free accession to all these collections instead of searching them through Delphion will be more time consuming. It is a question of deciding what we do prefer: saving time or money.

Finally, the possibility must be mentioned to freely register at Delphion with access to US patents and to the search by number to international patents. The problem is that to search by number, you previously need to have searched in another database to find out the number!.

Búsquedas de patentes: la tierra no es redonda, es larga y ancha


En el artículo anterior hemos visto los tipos de búsqueda de documentos según nuestras necesidades. Vamos a ver dónde encontrar lo que queremos. Hay muchas colecciones de documentos y hay que conocerlas para saber qué nos ofrece cada una.

Muchas entidades públicas y privadas ofrecen el servicio de búsquedas. Ante tantas opciones tendemos a pensar que cuando pagamos más por un servicio, debe ser porque es mejor, aunque no tiene por qué ser cierto. Vamos a comentar hoy una de las herramientas de búsqueda de pago más utilizadas: DERWENT.

Decir Derwent es decir Thompson Reuters. Pero se puede acceder a Derwent a través de otras plataformas como Questel, Delphion, Dialog o STN. Podemos perdernos fácilmente en esta maraña de posibilidades, datos, referencias. En ella encontramos diversas opciones de suscripción y búsqueda según si nos interesa una materia específica (química, electrónica, etc..), si nos interesa el texto completo de documentos, si nos interesan las patentes, la literatura científica o ambas, si nos interesa un periodo de tiempo específico, o queremos obtener documentos con un tipo de listado concreto etc.

No obstante como principales opciones en Derwent tenemos la Web of Science, el Derwent World Patent Index (DWPI), y el Thompson Innovation, que comentaremos a continuación.

Podemos suscribirnos a la Web of Science: Dentro de la colección de artículos, libros, patentes etc, el 78 % del contenido pertenece a ciencias naturales, el 22 % restante a ciencias sociales, arte y humanidades. Además, dentro de Web of Science podemos elegir disciplinas limitando la búsqueda en bases más concretas como Biological Abstracts, CAB Global Health, Derwent Innovation Index, Inspec, Medline, Web of Science Core Collection…

Si queremos saber más sobre el contenido de cada uno de estas sub-colecciones, podemos visitar Por ejemplo, por citar una de ellas: en BIOSIS Citation Index encontraremos artículos de más de 5.300 revistas y publicaciones desde 1926, más de 21 millones de registros, más de 2,6 millones de documentos, de meetings y conferencias, patentes estadounidenses etc sobre ciencias de la vida.

Otra de las sub-colecciones mencionadas, Inspec, incluye contenidos de física, tecnología eléctrica / electronica, informática, ingeniería de control,   tecnología de la información, o ingeniería mecánica de producción, y es actualizada semanalmente.

Un último ejemplo de estas colecciones incluidas en la Web of Science es el Derwent Innovations Index (DII), que incluye la opción de busca de patentes citadas al unificar los datos del Derwent World Patents Index (comentado a continuación) y el Derwent Patents Citations Index.  DII también permite buscar por compuestos químicos gracias al Derwent Chemistry Resources.

Es decir, cualquiera de estas sub-colecciones de la Web of Science es un mundo en sí misma.

Podemos suscribirnos a la segunda opción: Derwent World Patents Index (DWPI), según ellos son la base documental de patentes más usada en el mundo. Y en realidad deber ser así, pues muchas universidades, organismos de todo tipo incluyendo oficinas de patentes como la española, la usan. Podemos registrarnos durante un mes gratis ¡menos da una piedra!. En la página web de Derwent encontramos un mapa (el que se muestra en este artículo) que nos lleva inmediatamente a ver la cobertura de la base de datos en cada país y la fecha desde la cual se recopila la información para ese territorio.

Con un clic sobre uno de las zonas coloreadas encontramos el listado de países para ese área, con un punto verde a la derecha si es un miembro del Convenio Europeo de Patentes (EPC) o un punto rojo si es miembro de la Organización Mundial de la Propiedad Intelectual (WIPO/OMPI), o ambos en caso de que el país pertenezca a los dos convenios. Pinchando aún sobre el nombre de los países que se ven en color azul accedemos a información adicional sobre su oficina de patentes etc.

Cada año se añaden al DWPI más de 1,5 millones de nuevas invenciones de más de 3,5 millones de patentes, procedentes de países miembros del EPC, de la WIPO o de oficinas de patentes nacionales.

Por ejemplo podemos encontrar datos de patentes de los siguientes países desde las fechas señaladas:

Argentina: desde 1975
Bélgica: desde 1963
Canadá: desde 1963
Checoslovaquia: desde 1963
Alemania: desde 1963
Alemania Oriental: desde 1964
Hungría: desde 1974
Filipinas: desde 1992
Vietnam: desde 2010
Unión Soviética, Reino Unido, Suiza: desde 1963

No olvidemos que países que ahora no existen produjeron muchas patentes y bibliografía científica durante su existencia, así que hay que incluirlos.

También hay que tener en cuenta DWPI para las búsquedas en química y farmacia, porque ofrece aspectos ventajosos respecto a otras, pues originalmente se creó la base para estas disciplinas.

A pesar de todo, lo más antiguo en DWPI es de 1963. ¡Hay patentes desde mucho antes que no debemos perder en una búsqueda de estado de la técnica!.

Hay que añadir que Thompson  para estas bases de datos, a diferencia de otras, genera sus propios resúmenes de los documentos y sus herramientas de búsqueda como las palabras clave. Esto se considera una ventaja en cuanto a que cada documento que va a formar parte de la base, ha pasado por las manos de un experto.

Thompson Reuters también ofrece una herramienta adicional que aúna de algún modo las dos anteriores al incluir bibliografía científica y patentes, llamada Thompson Innovation: incluye literatura científica y patentes de Europa, América y Asia, el Derwent World Patent Index, comentado anteriormente, e INPADOC (base de datos de la Oficina Europea de Patentes que comentaremos otro día). Hay tres tipos de suscripciones según el alcance y resultado de las búsquedas que nos interesen: Analyst, Pro y Express. Para saber realmente el precio de cada suscripción es necesario contactar directamente con Thompson Reuters y preguntar. Para todas las suscripciones hay un mínimo de información (una ingente cantidad) disponible que es el Core Patent Data cuyo contenido se puede ver en:
