Fenwick & West was founded in 1972 in the heart of Silicon Valley—before “Silicon Valley” existed—by four visionary lawyers who left a top-tier New York law firm to pursue their shared belief that technology would revolutionize the business world and to pioneer the legal work for those technological innovations. In order to be most effective, they decided they needed to move to a location close to primary research and technology development. These four attorneys opened their first office in downtown Palo Alto, and Fenwick became one of the first technology law firms in the world.  MORE >

Fenwick Develops New Patent Practice Around AIA Post-Grant Proceedings

Mountain View, CA (August 21, 2012) - On September 16, 2012, a year from the date of enactment, many provisions of the Leahy-Smith America Invents Act (AIA) will go into effect. Fenwick & West is poised to help clients navigate the most significant modification to the U.S. patent system in 60 years. In particular, the firm is focused on revision and expansion of post-grant opposition proceedings and has built a new practice area around developing business focused strategies for dealing with patent disputes under the new rules.

The Post-Grant Proceedings Practice, co-chaired by Rajiv Patel and Stuart Meyer, leverages extensive experience in patent reexamination proceedings and parallel litigation to best position companies in the evolving IP management landscape. The result is a cost-effective approach to resolving disputes over patent validity and navigating the opposition process in pursuit of business objectives.

The America Invents Act (AIA) makes fundamental changes to the patent filing system, moving the U.S. from a “first to invent” to a “first to file” system which is more consistent with international practices. In addition, the AIA eliminates interference proceedings and develops post-grant opposition proceedings. The newly created Patent Trial and Appeal Board (PTAB) has been designed to leverage the U.S. Patent and Trademark Office’s regulatory and technical expertise in patent reexamination by expanding its scope to include other validity disputes in quasi-litigation contexts. This will potentially allow parties to resolve validity disputes without introducing the high costs and complicated proceedings of in-court litigation to the opposition process.
