Bloomberg/BNA has published its second quarter analysis of the ROL Group patent market data. Our data continues to be a valuable resource for those seeking to buy or sell patents. Our latest annual report can be downloaded here.

"... Possibly the largest asset transfer during the quarter involved two packages containing 261 U.S.-issued patents sold by Wilk Patent Development Corp. and its president, Peter J. Wilk, to CHF Technologies Inc., which does business as BioVentrix Inc., a cardiovascular device firm.

Wilk previously sought to sell about 25 cardiovascular patent assets on the brokered market through ICAP Patent Brokerage, according to a September 2015 press release. The patents “pertain to heart and vascular surgery, cardiothoracic surgery, coronary artery bypass procedures” and numerous other cardiovascular procedures, according to the release.

Because of the PTO recording lag, it’s not clear how many of the Wilk patents BioVentrix actually purchased.

Twitter also purchased patent assets from the defensive patent aggregation firm Allied Security Trust during the quarter. The package included 14 patent assets, including 7 U.S.-issued patents."
