Companies cannot take out patents. Ther inventor takes out the patent and then assigns it to the compny. As I recall, either the BSTJ or the Bell Labs Record in each issue published a list of patents applied for and those granted, with the names of the inventors. I think this was done uniformly on all inventions that were patentable. Wes Leatherock snipped-for-privacy@aol.com snipped-for-privacy@yahoo.com
