The Federal Circuit has declined to overturn the invalidation of an Intellectual Ventures (IV) wireless security patent (7,496,674) in an inter partes review (IPR) filed by Ericsson (2015-1947). In a summary affirmance issued on August 16 without an accompanying opinion, the court upheld a May 2015 final decision by the Patent Trial and Appeal Board (PTAB) that cancelled claims 1-22 of the ‘674 patent as anticipated by and obvious over prior art (IPR2014-00527). IV had sought to reverse this decision partly on the basis that one of these references, an article sponsored by the Department of the Air Force, did not anticipate claims 1-6 and 10-22 of the ‘674 patent and did not qualify as prior art. The NPE also challenged the Board’s ruling that claims 1-22 are obvious over two other references.
