Case History

Proving University of Kansas inventorship of cancer drug Velcade — Winning a four year long case getting a University of Kansas professor and research assistant named as co-inventors on two NIH patents claiming the formulation for a multibillion dollar anticancer drug called Velcade. Opponents included NIH licensees Johnson & Johnson, Millennium Pharmaceuticals, Inc. and Takeda Pharmaceuticals Co. Ltd.
Forcing An Opponent Patentholder to Pay Our Client's Attorneys Fees — Mr. Atkins won a three week jury trial for a Swedish client who was sued for over $200M for patent infringement and other related allegations and got it affirmed at the Federal Circuit. He then pursued, won, and collected attorneys fees and costs of over $1.2M. District Court's decision stated "Defendant's counsel could not have achieved a better result for their client," and that his trial team's "time records in this case . . . were all reasonable and reasonably necessary for [the Swedish company] to defend this case."
Turning The Tables And Getting The Plaintiff/Patentholder To Be The Accused Infringer - Then Winning At Trial — A major Chinese competitor sued his U.S. client for patent infringement in D.C. Mr. Atkins convinced his client to countersue in the Eastern District of Virginia (known as the "Rocket Docket"). There, he won a three week jury trial for his client and also won a summary judgment of non-infringement in D.C. for his client.
