Challenge a patent's validity 
with credible Prior Art

A new approach to effectively defend 
against higher quality patents

Chipworks Prior Art Technical Library provides 
the evidence you need to boost your patent invalidity arguments.

Companies accused of patent infringement can often prove patent invalidity by finding prior art in easy to access public information such as patents, technical literature and conference papers. But today, due to the high court costs and the risk of PTAB (Patent Trial and Appeal Board) invalidation, patent owners are much more selective about the quality of patents they are asserting. To effectively defend yourself against these higher quality patents requires a new approach.

Whether it is for a court trial or an inter partes review (IPR), the Chipworks Prior Art Technical Library takes patent invalidation investigation to a deeper level. It contains over 1,800 detailed circuit design and process analysis reports, dating from 1990 to 2011, on a wide range of real-world, high-technology products and semiconductor chips.

Showing evidence of real-world implementations of the claims in question make a compelling prior art defense. It can also bolster arguments to significantly reduce the scope of claims in claims construction/Markman rulings. Since real-world examples are part of a larger system, it is often possible to show that the prior art implementation limits the scope of multiple claims, improving the chances of proving invalidity.

The Chipworks Prior Art Technical Library is an important tool to assist in 
your defence against high quality, difficult to refute patent assertion claims.
