Attack on Helferich Patent Licensing/Wireless Science Patent, among the Reexamination Requests Filed Week of May 7, 2012
| May 7, 2012
Helferich Patent Licensing has been extremely aggressive and extremely successful in asserting its portfolio of mobile wireless communications patents against the world’s media and retail giants. According to the patent search outfit M-CAM, Helferich has sued licensed 42 companies, including Apple, Dell, Hitachi, LG, Microsoft, Motorola, NEC, Nissan, Nokia, Samsung, Sharp and Toshiba. In a case filed in 2010, Helferich sued CBS for infringement of 21 patents. This February, it obtained U.S. Patent No. 8,116,741, adding it to the CBS litigation and to six other infringement actions. On Friday CBS and the other defendants in those cases, requested reexamination of the ‘741 patent (see inter partes Request No. (1)).
This is by no means the first reexamination asserted against Helferich, who so far appears to have been quite adept at overcoming the prior art asserted against and adding numerous claims to its patents in reexamination.

The Risks of Inconsistent Arguments in Parallel Proceedings
| May 3, 2012
A patentee, who is simultaneously pursuing an infringement in District Court and defending its patent in a reexamination proceeding at the PTO, often faces the temptation to construe its claims broadly in court but narrowly at the PTO. The risks of yielding to that temptation are illustrated in Judge Susan Illston’s claim construction decision Tuesday in Kilopass Technology v. Sidense (2102 U.S. Dist. LEXIS 60973).
There, in an earlier Markman hearing, the patentee had argued that the terms “column bitline” and “row wordline” (in claims for a semiconductor memory cell) were interchangeable, and further that they should be defined identically as “a line that connects to one terminal of each memory cell in a memory array.” The effect of the patentee’s proposed claim construction was to overcome: specifically, the fact that the arrangement of the “column bitline” and “row wordline” in the accused semiconductor was precisely opposite the arrangement of those components recited in the asserted claims. Judge Illston initially construed the claims in favor of the patentee.
Challenges on Intellectual Ventures Computer Circuit Patents among the Reexamination Requests Filed Week of April 23, 2012
| April 30, 2012
An undisclosed party requested reexamination of two computer circuits patents owned by Intellectual Ventures (see ex parte Request Nos. (13) & (14)). IV patents in this technology have come under attack by Xilinx in recent times, and it was quite possibly Xilinx that filed these requests. Incidentally, one of the IV patents was originally owned by LG Semicon and the other by Motorola.
Requests were also against four auto-navigation patents owned by Beacon Navigation (see ex parte Request Nos. (8) to (11)). Beacon has sued quite a few auto-makers in Delaware for infringement of those patents, including Honda, Porsche, BMW and Ford.
