Prior Art Searches & Evaluations

In patent infringement litigation and post grant proceedings, finding and asserting key prior art may dramatically affect the strength and corresponding value of the case.   As a patent infringement defendant, it is often imperative that a thorough prior art search be conducted competently and effectively.

Even in patent prosecution matters, a prior art search is important to assess the scope and patentability of an invention.  The better the prior art search, the greater the opportunity to carefully craft the claims and defend against later assertions of invalidity.

The patent attorneys, agents and technical specialists at Lewis Roca Rothgerber Christie have unparalled expertise in overseeing and personally conducting global prior art searches.  With a deep bench of personnel with strong and focused technical backgrounds, we are at once able to communicate and understand the inventions at issue.  We couple that with decades of experience in conducting searches for non patent publications, which often elude routine searches, as well as the examiners in the various patent offices.  Our team includes members who are fluent in Japanese, Mandarin and Korean, to effectively communicate with overseas searchers and to personally conduct searches and evaluate the search results.  We have deep connections with academia at multiple universities and research institutions to obtain highly focused assistance where needed for the most challenging searches.  We also have extensive experience in carrying out searches through crowd sourcing and incentive based approaches.
