RPX data indicate that since 2016, NPEs have collectively launched over 80 separate litigation campaigns asserting patents received from Intellectual Ventures LLC (IV). Meanwhile, the outflow of patents from IV persists, and divestments executed last year (primarily during the fourth quarter of 2019) continue to be recorded with the USPTO—many preceding the start of new NPE campaigns.

Following a notice letter allegedly sent to Broadcom in April 2018 without response, Complex Memory LLC, an affiliate of Texas monetization firm IPValuation Partners LLC (d/b/a IPVal), has filed suit against the company in the Northern District of California (5:18-cv-07530). The complaint asserts five patents, generally pertaining to chip operation and memory access, already at issue in the campaign, with the NPE identifying certain Broadcom products “incorporating ARM Cortex-A9, A15, A57 and other ARM Cortex-A architectures” as the accused products, specifically identifying Broadcom’s “BCM5871X, BCM58712, BCM58713, BCM4707, BCM4708, BCM4709, BCM5301X, BCM11107, and BCM5862X families of products”. This new case joins suits filed in the latter half of 2018 against Renesas (in July), against Lenovo (Motorola Mobility) (in September), and STMicro (in November).

Last year’s suits winding down, Complex Memory LLC, an affiliate of Texas monetization firm IPValuation Partners LLC (d/b/a IPVal), has added another suit in 2018. The NPE accuses STMicro (1:18-cv-06255) of infringing four of the seven patents-in-campaign through the provision of mobile chipsets with certain features related to memory management. Those accused products include the STiH416 system-on-chip, targeted over its alleged inclusion of an ARM Cortex-A9 Core and its cache memory; certain STM STM32F100xx Series microcontrollers (MCUs), which allegedly include a direct memory access (DMA) controller; the Telemaco3P family of microprocessors (designed for automotive telematics), which allegedly include certain types of DDR memory; and the STiH series of systems-on-chip, targeted over certain energy conservation features of the Cortex-A9. The asserted patents, of disparate origins but all received from Intellectual Ventures LLC (IV), generally relate to chip operation and memory access.

Earlier this year, RPX flagged an SEC filing by NPE Quest Patent Research Corporation (QPRC) that revealed a financial stake held by Intellectual Ventures LLC (IV) in QPRC’s litigation. A disclosure filed with the court this week in an IPValuation Partners LLC (d/b/a IPVal) case suggests that IV—which has assigned at least 80 US assets to IPVal to date—may have an interest in the success of additional NPE campaigns.

The 2017 cases in its sole litigation campaign either stayed in light of settlement negotiations or having settled already, Complex Memory LLC has added a second 2018 suit, this one against Lenovo (Motorola Mobility) (1:18-cv-06255) in the Northern District of Illinois. Last month, the NPE, an affiliate of IPValuation Partners LLC (d/b/a IPVal), sued Renesas in the Northern District of California, while cases against SVTronics and Texas Instruments (TI) (on July 6) and Huawei (on July 26) were dismissed with prejudice in July. A November 2017 suit against ZTE has been stayed to facilitate settlement. All five cases have asserted the same five patents, broadly concerning various aspects of chip operation and memory access, with the suit against Renesas throwing in two additional such patents. At issue have principally been smartphones based around TI OMAP or ARM core architectures—in the complaint against Motorola Mobility, mobile devices “incorporating ARM Cortex-A53 and other ARM Cortex-A architectures, including Qualcomm Snapdragon, Kryo and Krait devices”.

Complex Memory LLC, an affiliate of IP Valuation Partners LLC (d/b/a IPVal), has added a third suit to the litigation campaign that it began last month, suing ZTE (3:17-cv-03196) in the Northern District of Texas over the same five patents, broadly concerning various aspects of chip operation and memory access. At issue are ZTE “mobile devices, such as smart phones, incorporating ARM Cortex-A53 and other ARM Cortex-A architectures, including Qualcomm Snapdragon, Kryo and Krait devices”. Complex Memory’s October cases were filed in the Eastern District of Texas against Huawei alone and SVTronics and Texas Instruments (TI) together; the defendants have requested extensions of the deadline to respond to the complaints against them.

Among the patent assignments recorded during the first week of November were multiple transfers from Intellectual Ventures LLC (IV)—two to affiliates of IP Valuation Partners LLC (d/b/a IPVal) (which currently has multiple ongoing campaigns asserting former IV patents), and one to a new NPE with an apparent connection to Cotman IP. The week also saw the recording of transactions between IQ Holdings, LLC and IPVal; Panasonic and PanOptis Equity Holdings LLC; and Microsoft and General Patent Corporation.

Earlier this year, Intellectual Ventures LLC (IV) signaled a move away from the purchase of additional patents, instead refocusing on the monetization of existing assets. A review of IV’s patent assignments over the last 12 months confirms that shift, as do IV’s recent litigation activities, which include an automotive campaign begun in March (its first new campaign since 2015). While there has been much speculation about the effect that IV’s decision to stop buying patents may have on the patent marketplace, just as interesting is what will come of its patent divestitures. RPX has observed the transfer of patent portfolios from IV to multiple other NPEs over the past year, including four of the top ten filers (by defendant count) in 2017: IP Valuation Partners LLC (d/b/a IPVal); Leigh M. Rothschild; Monument Patent Holdings, LLC; and Equitable IP Corporation. Each has initiated its own litigation campaigns asserting patents acquired from IV, beginning with Equitable IP back in October 2016, and including three launched by IPVal during the first half of this October alone.

Yet another affiliate of IP Valuation Partners LLC (d/b/a IPVal) has launched a litigation campaign, the sixth in October alone. Complex Memory LLC has filed complaints against Huawei (2:17-cv-00700) and SVTronics and Texas Instruments (TI) (2:17-cv-00699), each asserting five patents generally related to chip operation and memory access. The NPE accuses Huawei of infringement through the provision of smartphones and tablets that incorporate ARM Cortex-A9, Cortex-A15, Cortex-A53, Cortex-A73, and/or other ARM Cortex-A architectures, and SVTronics and TI of infringement through the provision of products incorporating ARM Cortex-A9 and/or ARM Cortex-A15 architectures. Complex Memory pleads that the latter two defendants are properly named in a single complaint because they both allegedly incorporate TI OMAP processors into the accused products, and because SVTronics purportedly integrates, “and sells products based on”, TI processor designs.

At a scheduling conference held on May 31, 2017 before District Judge Rodney S. Gilstrap in the Eastern District of Texas, plaintiff Hypermedia Navigation LLC, an affiliate of monetization firm IP Valuation Partners LLC, and defendant Yahoo, nearing acquisition by Verizon, indicated that a joint motion to transfer their case to the Northern District of California had been filed. Judge Gilstrap had that same day issued an order requiring the parties to address the effect, if any, of the US Supreme Court’s TC Heartland decision on Yahoo’s April motion to dismiss for improper venue, itself already premised on a TC Heartland theory—that is, on a reading of the venue statutes that restricts corporate residence to the state of incorporation (Delaware for California-based Yahoo). On June 1, the court granted the joint motion, and four days later, the case (3:17-cv-03188) was opened in the Northern District.
