In reference to the patent: US 2012/0138076 A1
Has this patent been granted? Please can I have as much information on this patent as possible?
The primary source of information is the USPTO Public Pair database which has a CAPTCHA and does not allow direct links to individual patents. On that site, Search for Application by Publication Number "US 20120138076 A1". The Image File Wrapper contains a large number of documents, but of particular note is an Abandonment on October 22, 2014. The reasons for abandonment will be in that publication, which is freely available. Also available is all of the correspondence between the examiner and the inventor. Only under very rare circumstances may an abandoned patent be revived.
