The chain-of-title of one or more of the assets included in the deal could be defective, one of the inventors has not transferred her rights to her employer. Some patents resulted from a collaborative arrangement and now are jointly owned. The seller could present a list that inadvertently missed several important patents. The Government could have funded any party along the chain of title, it could prevent the buyer from manufacturing outside of the U.S. Is any of the patents subject to anti/conditioned/restricted assignment clause? Has any of the assets expired due to non-payment of maintenance fees? How long would it take to check 500 patents, and how much would it cost?


With PatenTrack all the above can be done within one week. Including review of prior litigation, PTAB, and even the technical scope of the claims.  We automated all that so you can do your job successfully.
