Intellectual property practice is rife with searches. We list below the more common searches that the entrepreneur will come into contact with or have occasion to use.
PATENT SEARCHES. There are different types of patent searches depending on what is being searched for.
Novelty or Patentability Searches. These searches help to answer the question: Can I get a patent on my invention. These searches encompass all prior art, whether dead, invalid, US or foreign. These searches typically only answer the first of the two main patentability questions, that is, whether the invention is novel in light of the prior art. The second question, much more murky, is whether the invention is obvious in light of the prior art. These searches cannot definitively answer that second question, but can give guidance to a patent professional, and perhaps suggest design around tactics.
Infringement Searches. Infringement searches are also called Right-to-Use Searches, Clearance Searches, or Freedom of Operation Searches. Whether you wish to get a patent or not, you will wish to know if producing and marketing your invention may infringe the claims of someone else’s patent. These searches are more narrow, because you don’t care about dead or expired patents, the relevant date range is the last 20 years, and if you are only interested in the US market, you don’t care about foreign patents. These searches are also more narrow than novelty and invalidity searches in that you only care about patents, not other types of prior art. Like invalidity searches, these searches focus on individual claims of patents.
Invalidity Searches. Invalidity searches seek to answer the question: Was the patent issued erroneously such that it should be invalidated. These searches, which focus on individual claims in a patent, are typically more time consuming than a novelty search. The focus is on finding prior art that existed before the patent application was filed, and which was not cited to or considered by the Patent Office during the examination of the patent application. Just like novelty searches, invalidity searches are not limited to patents and patent applications, but anything which may be prior art, such as an industry report, or pre-existing apparatus, or trade journal article.
State-of-the-Art Searches. These are very different types of patent searches. The point of these searches is to allow researchers and developers to see what is the current state of development in a particular field of endeavor.
TRADEMARK SEARCHES. Also called Trademark Clearance Searches and Name Availability Searches, this type of search is performed to see if a name is appropriable for use as a trademark, both from the perspective of eligibility for registration and from the perspective of avoiding using someone else’s mark. These searches typically search not only State and Federal trademark and corporate name databases, but also yellow pages, phone books, and the Internet, among other sources.
COPYRIGHT SEARCHES. Copyright searches are often the hardest of all searches to be confident about. You can search titles and authors at the Copyright Office, and you can do Google, Google/Scholar, and Google/Book searches. There also exist specialty libraries for various types of artists that can and should be checked, such as for music and the visual arts. But any type of search will necessarily omit huge swaths of published material that simply (a) has not been registered for copyright (even though it is copyrighted) and/or (b) has never been put on the internet.
