Publicly traded Prism Technologies Group, Inc. (PTG) has seen two of its key campaigns crippled by invalidity rulings, as the NPE’s struggle to stay in business in spite of rapidly dwindling resources may ultimately blunt the potential impact of a recent appeal victory. In late July, PTG subsidiary Secure Axcess LLC dismissed cases against nearly all of its campaign defendants with prejudice after the Federal Circuit upheld a ruling by the Patent Trial and Appeal Board (PTAB) that cancelled all but one of the asserted patent’s claims. Meanwhile, in the campaign waged by PTG subsidiary Prism Technologies LLC, the Federal Circuit upheld in late June the invalidation of two patents-in-campaign under Alice in a victory for T-Mobile, later declining to overturn a previous, $30M verdict against Sprint involving those same patents. However, Sprint continues to fight that ruling, and PTG’s litigation costs continue to accumulate even as recent reporting on its financial results indicate that it is running out of cash.

The Federal Circuit has affirmed an October 2015 non-infringement verdict for T-Mobile in a case (8:12-cv-00124) brought by Prism Technologies LLC, also ruling that the asserted patents (8,127,345; 8,387,155) are invalid under Alice (2016-2031, 2016-2049). In an opinion issued on June 23, the Federal Circuit held on cross-appeal by T-Mobile that the ‘345 and ‘155 patents are invalid as directed to the abstract idea of “providing restricted access to resources” without the addition of an inventive concept. The Federal Circuit then denied Prism’s appeal of the non-infringement verdict as moot in light of its invalidity ruling.

Prism Technologies subsidiary Secure Axcess, L.L.C. filed a new round of litigation against Dell, Dimension Data Cloud, Ericsson, Fujitsu, and HP Enterprise. Two patents are asserted in the cases, which concern transmitting and processing data packets (6,108,713, 6,172,990). At issue are defendants’ networking services, including hardware and software that provide networking solutions. Secure Axcess has not previously asserted these patents or any of the other three patents in the portfolio. The entity has asserted a number of patents related to networking technology in its other litigation.
