US-Based Prior Art Searches Since 1997

Founded in 1997 by U.S. Patent Attorney Robert L. Risberg, we are a U.S. patent search firm.  We focus on prior art searches for patent validity, product clearance, and patentability.

Mr. Risberg received a B.S in Electrical and Computer Engineering in 1987 from the University of Wisconsin.  He received his J.D. in 1990 from the University of Wisconsin Law School, where he served as Articles Editor on the Wisconsin Law Review.  He is a member of the State Bar of California and is registered to practice before the U.S. Patent and Trademark Office.

Qualified Patent Information Professional

The Qualified Patent Information Professional (QPIP) certification sets professional standards for patent searching.  Earning this credential requires passing a two-day examination or documenting at least ten years of experience.  Mr. Risberg holds the QPIP credential.

Litigation Background

Mr. Risberg was an associate for the law firms of Townsend and Townsend and Crew LLP (1990-94) and Weil, Gotshal & Manges LLP (1994-97).  He was also Of Counsel to the law firm of Isbester & Thackray LLP (2002-08).

While at the Isbester firm, he was a member of a three-lawyer team representing plaintiff in a successful patent infringement action relating to phacoemulsification equipment (Advanced Medical Optics, Inc. v. Alcon, Inc.).

The jury awarded $94.8 Million, one of the largest jury verdicts of 2005.  The court later trebled damages.  The case settled with payment to AMO of $121 million and cross-licenses.
