Collabo vs Sony Litigation Update

The US Court of Appeals publishes its opinion on Collabo Innovation appeal on the verdict in its lawsuit against Sony. The appeal claims mostly talk about 1999 US7,023,034 patent originally filed by Panasonic and later acquired by Collabo. The appeal argues about the definition of trapezoid shape of the lightpipe, as presented in prior art.

The court concludes "We have considered Collabo’s remaining arguments and find them unpersuasive. For the foregoing reasons, we affirm the Board’s construction of “reflecting wall” and its conclusion that claims 3 and 12 are unpatentable as obvious."
