I'll research this company before writing the profile.
Patriot Scientific Corporation (OTC: PTSC) was a Delaware corporation organized March 24, 1992 (a predecessor business dates to 1987), headquartered in Carlsbad/San Diego, California. It was a small, thinly traded OTC Bulletin Board/Pink company — IEEE Spectrum described it in 2004 as a "seven-person firm." It is no longer an IP company: in August 2020 it was reverse-merged with a private biotech, and effective November 30–December 1, 2020 it renamed itself Mosaic ImmunoEngineering Inc., switched its ticker to CPMV, and is now a development-stage cancer-immunotherapy company. Roughly 6 employees are reported; no meaningful revenue.
Operations. Patriot's pre-2020 business was primarily patent licensing, not manufacturing. Its historic product efforts included the ShBoom-derived PSC1000 microprocessor family, the Ignite/Inflame processor designs, data-communications products, and, earlier, ground-penetrating radar — but these generated little revenue. Its principal asset was a co-owned interest in the Moore Microprocessor Patent (MMP) Portfolio: seven U.S. patents (e.g., U.S. 5,809,336 on separate CPU/I/O clocking; 5,784,584; 6,598,148) plus European and Japanese counterparts, jointly held with Technology Properties Ltd. (TPL Group) and inventor Charles H. Moore. The portfolio was commercialized by TPL's Alliacense unit and a 50/50 joint venture (Phoenix Digital Solutions) under a 2005 master agreement that gave TPL exclusive licensing and enforcement rights. Licensing revenue included roughly $24 million collectively from Intel, AMD, and Hewlett-Packard, and licensees eventually numbered in the dozens (Fujitsu, Sony, NEC, Nokia, SanDisk, Casio, and others).
Litigation posture. A hybrid, leaning monetizer. Patriot appears as plaintiff in 3 tracked cases (asserting the MMP patents) and defendant in 2 (declaratory-judgment actions brought by targets). It filed infringement suits in December 2003 in N.D. Cal. (Oakland) against Sony, Fujitsu, Matsushita, NEC, and Toshiba; Intel responded with a DJ suit, and 20 Japanese manufacturers filed five DJ actions. Enforcement then shifted to TPL in the plaintiff-friendly Eastern District of Texas (Marshall, Judge T. John Ward), where the parallel N.D. Cal. actions were stayed.
Notable context. Tracked matters include Technology Properties Ltd. et al. v. Fujitsu (E.D. Tex. 2005), Patriot Scientific v. Sony Electronics (N.D. Cal.), Intel Corp. v. Patriot Scientific, and the Japanese manufacturers' consolidated DJ suits naming Moore. Related MMP litigation continued through HTC Corp. v. Technology Properties Ltd. (N.D. Cal., and an ITC action) and a 2011 settlement resolving Patriot–TPL joint-venture disputes. The legacy IP business was wound into the inactive subsidiary Patriot Data Solutions Group.
Barco N.V. brought a declaratory judgment action on three MMP patents (specific patents not confirmed in the narrative). The case was related to and consolidated with the HTC and Acer/Gateway actions.
Declaratory judgment action filed December 1, 2008, by Barco N.V. against Technology Properties Ltd., Patriot Scientific Corp., and Alliacense Ltd. concerning the MMP portfolio. Various orders issued in 2010–2011, and the '584 patent was non-asserted via covenant. The narrative does not clearly identify the '915 patent as specifically asserted in this action.
HTC filed a declaratory-judgment action of invalidity/non-infringement as to the '336, '584, '749 and '148 patents. TPL counterclaimed for infringement of the '336, '749, '148 and '890 patents. After trial, the jury found HTC literally infringed claims 6, 7, 9, 13, 14 and 15 of the '336 patent with a $958,560 lump-sum royalty, not willful; JMOL denied and final judgment entered for TPL. Other patents were dismissed or carved out.
ASUSTeK brought a declaratory judgment action naming US 5,440,749, US 5,809,336, US 5,809,623, US 5,809,638, and US 5,784,584; the complaint was amended July 10 and September 23, 2008. The case settled December 18, 2008, and all claims were dismissed February 25, 2009.
HTC filed a declaratory judgment action against TPL, Patriot Scientific and Alliacense; the '890 patent was added by amended complaint on July 10, 2008. TPL counterclaimed for infringement of '336, '749, '148 and '890. On Sept. 19, 2013, all claims relating to the '890 patent were dismissed by stipulation; only the '336 patent reached the jury.
One of five declaratory judgment suits filed in December 2005 by roughly 20 Japanese electronics manufacturers against Patriot, TPL and Charles Moore, seeking declarations that the '584, '336 and '148 patents were not infringed and invalid.
Declaratory judgment action reported by heise; case number, patents, and outcome not verified.
Related N.D. Cal. declaratory judgment action by ASUSTek/ASUS against TPL, Patriot, MCM Portfolio, and Alliacense, related to the Acer and HTC cases. The narrative does not provide an outcome.
Intel filed a declaratory judgment action against Patriot in the Northern District of California in February 2004. It was resolved through the 2005 MMP portfolio licenses to Intel and AMD. The '703 connection is portfolio-level.
A group of about 20 Japanese electronics manufacturers filed five declaratory-judgment suits in December 2005 in the Northern District of California against Patriot, TPL, and Moore, seeking non-infringement and invalidity of three jointly owned MMP patents. The actions were consolidated/litigated through 2008-2010 before Judge Fogel. The '703 connection is portfolio-level and not identified as one of the three litigated patents.
