In reference to the patent: US20100203636

1 Answer 1


Patent application is abandoned due to "Failure to Respond to an Office Action". It is expired during the examination process.

You can use the USPTO's public PAIR database(https://portal.uspto.gov/pair/PublicPair) for legal status. If the patent is active then the patent term is 20 years from its own filing 35 U.S. Code § 154 (a)(2)
