A jury in the Eastern District of Texas has issued a verdict of infringement in litigation brought by a subsidiary of Intellectual Ventures LLC (IV) against T-Mobile and Ericsson. The jury found that the defendants both infringed at least one of the patents-in-suit, T-Mobile through its LTE network and Ericsson through related LTE telecommunications equipment, awarding damages of $34M as to the former and $9M for the latter. That verdict comes after a series of recent setbacks for IV in the same litigation campaign, including the Federal Circuit’s affirmance of a T-Mobile Alice win last month and the partial grant in September of an Alice challenge brought by T-Mobile and SoftBank (Sprint). The European leg of that campaign has also run into trouble, with a noninfringement verdict reportedly issued last year in litigation against Deutsche Telekom, Telefonica, and Vodafone.
The past two years have seen a dip in US litigation filed by Intellectual Ventures LLC (IV), which started only one new American campaign in 2017 and none the year before. However, available court records indicate that an offshoot of one of the NPE’s oldest remaining US campaigns—started in 2011 and targeting a host of wireless carriers—also remains active in Germany. Filed documents indicate that appeal hearings were held as recently as January 24 in cases against European carriers Deutsche Telekom, Telefonica, and Vodafone. The related US campaign is one of just two in which IV filed new litigation in 2017, during which time the NPE accelerated the pace of divestitures from its massive portfolio.
Intellectual Ventures LLC (through its subsidiary Intellectual Ventures II LLC) (IV) has filed a sixth lawsuit (2:17-cv-00661) against Deutsche Telekom (T-Mobile) in the same litigation campaign. The new case asserts six wireless communications patents, not seen previously in litigation, against the carrier, together with LM Ericsson. IV concurrently filed a new case (2:17-cv-00662) against Ericsson, Nokia (Alcatel-Lucent), and SoftBank (Nextel Operations, Sprint Spectrum), asserting the same six patents. While Ericsson was not named as a defendant in earlier cases in this campaign, Ericsson has brought nearly half of the 43 petitions for inter partes review (IPR) challenging various patents-at-issue.
Intellectual Ventures LLC (through its subsidiary Intellectual Ventures I LLC) (IV) has filed yet another lawsuit against Deutsche Telekom (T-Mobile) (2:17-cv-00577), this time explicitly naming LM Ericsson with T-Mobile. The new complaint asserts four patents not previously seen in any litigation, including in this campaign, which IV began in September 2011 and now concerns over 55 patents asserted against wireless carriers and camera makers, among others. Despite not being named as a defendant in district court, Ericsson has brought nearly half of the 43 petitions for inter partes review (IPR) challenging patents in the campaign. This new case against T-Mobile and Ericsson comes as IV and AT&T have requested another extension of an earlier stay, this time to mid-October, in order to facilitate finalization of an agreement ending the parties’ disputes.
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.
New suits filed by Intellectual Ventures I LLC (IV) accuse AT&T (1:15-cv-00799) and T-Mobile (1:15-cv-00800) of infringing a data transmission patent that has been asserted against the companies in the past. In two separate complaints, IV alleges that the defendants offer cellular services that infringe the 5,960,032 patent by using spread spectrum channel coding.
