Post Media Systems LLC has kept its sole litigation campaign alive, filing suit against SoundCloud (2:16-cv-01269) after a September settlement with iHeartMedia and an October settlement with Spotify. All patents in a family of five (7,069,310; 7,472,175; 8,015,263; 8,725,832; 8,959,181) are asserted in the new complaint, subsets having been asserted against the prior two defendants. The family generally relates to managing media files for playback over a computer network, with the defendants accused of infringement through the provision of their music and radio online services and related apps. Post Media’s is one of seven litigation campaigns, in disparate technical fields, initiated by entities managed by Erik Stamell, now the president of NPE Equitable IP Corporation, since November 2015.

High Frequency Trading Systems LLC (HFTS) has filed four new cases in the campaign it began in late 2015, asserting a single patent (7,231,363) generally related to electronically managing the exchange of financial instruments. Knight Capital (KCG BondPoint) (2:16-cv-13082), Liquidnet (2:16-cv-13077), MarketAxess Holdings (2:16-cv-13052), and MTS Markets (2:16-cv-13084) are accused of infringement through provision of online trading platforms. HFTS’s new filings provide just one example of the recent activities of its manager, Erik Stamell.

In the second half of June 2016, RPX saw over 20 patent transfers to NPEs recorded with the USPTO. A number of those transactions involved patents that have been asserted in litigation against operating companies—some as recently as this past week.

ASUS (1:16-cv-00576), Bank of America (1:16-cv-00574), Cisco (1:16-cv-00577), IBM (1:16-cv-00578), and Ericsson (1:16-cv-00575) are the latest defendants to be added to the litigation campaign of Digital Audio Encoding Systems, LLC (DAES). A single digital signal encoding patent (7,490,037) is at issue, with the latest defendants accused of infringement through the manufacture and sale of Android devices (smartphones, tablets, wearables, etc.) pre-installed with Google Music Play (ASUS and Ericsson) or the use of Cisco’s WebEx collaboration product (Bank of America, Cisco, and IBM). DAES is one of multiple entities recently formed by Erik Stamell, four of which have so far launched litigation.

Digital Audio Encoding Systems, LLC (DAES) has more than doubled the number of defendants in its sole litigation campaign, filing new complaints against Alphabet, Amazon, Best Buy, BlackBerry, eBay, HTC, Huawei, Lenovo (Motorola Mobility), LG Electronics, Nokia, Sony, T-Mobile, Toshiba, Verizon, Wal-Mart, and ZTE. The NPE asserts a single digital signal encoding patent (7,490,037), accusing the defendants of infringement through the manufacture and sale of various Android devices (smartphones, tablets, wearables, etc.) that come pre-installed with audio or video streaming apps, including Google Music Play, Samsung Milk Music, Slacker Radio, and/or Youtube. DAES is one of many entities recently formed by Erik Stamell, four of which have so far launched litigation.

This past week saw the number of newly formed Texas NPEs managed by Michigan attorney Erik Stamell to launch litigation double, from two to four. First, Post Media Systems LLC asserted three patents (7,069,310; 7,472,175; 8,725,832) in new cases against iHeartMedia (2:16-cv-00649) and Spotify (2:16-cv-00650). Those patents-in-suit generally relate to managing media files for playback over a computer network, with the defendants accused of infringement through provision of their music and radio online services and related apps. Next, Optical Measurement Systems, LLC accused Broadcom (Avago) (1:16-cv-0468) and Marvell (1:16-cv-00469) of infringing a single patent (8,838,822), generally related to translating packet-based data into a serial data stream, through the sale of the defendants’ optical transceivers. Also this week, Digital Audio Encoding Systems, LLC added seven defendants to a campaign that it kicked off one month ago by filing a case against Apple. With nearly 20 new NPEs formed in Texas since August 2015, more Stamell-managed litigation campaigns seem destined to follow in 2016.

In the first half of June 2016, RPX saw six patent transfers to NPEs recorded with the USPTO. At least one of those transactions involved a patent that has already been asserted in litigation.

In the second half of May 2016, RPX saw five patent transfers to NPEs recorded with the USPTO. One of those transactions involved a patent that has already been asserted in litigation.
