Levien v. Levien v. Katayama et al.

Levien v. Levien v. Katayama et al.

B.P.A.I. (2000)

Our representation of Canon Inc. resulted in a favorable decision by the Board of Patent Appeals and Interferences on August 3, 2000 granting the Canon inventors, Katayama et al., priority on their halftone imaging invention. We successfully persuaded the Board that Levien did not prove earlier conception and diligent reduction to practice, and that the alleged corroborating testimony failed to show possession by Levien of every feature of the invention. We further proved that even if Levien had established priority, he still would have lost, because Levien’s two year delay in filing meant he suppressed the invention.
