Originally posted by Votesh If I'm not mistaken the patents would be the property of Hoya, and not the Pentax part of Hoya. So buying Pentax for patents would only matter for future patents, and to that end, that would largely be due to Pentax employees, and not the company itself. If Canon was that concerned, it could just lure Pentax employees with promises of higher wages, rather than buy an entire company just for the collective knowledge and unfinished research of its employees.
Also, I think the premise of the rumor is crazy. If either of these companies was going to buy Pentax to shut it down, or for intellectual property, they would have done it instead of letting Hoya buy Pentax. It would have been much cheaper back then.
While I think talk of Canon buying Pentax from Hoya is ludicrous, the exact ownership of the patents is of little consequence. The sale could be structured to include any Hoya assets that the buyer and seller could agree on. So, if Canon wanted a particular patent, along with Pentax, Hoya could include that patent.
Since Pentax is no longer a seperate corporate entity, and just a division within Hoya corporation, everything, from the patents, to the production facilities, to the chairs the engineers sit on, belongs to Hoya. Any sale would include a rather detailed description of exactly what was being sold.
The fact the Hoya folded Pentax into itself, rather than keeping it as a wholly-owned (but seperate corporate entity) subsidiary, was and is, to me, a sign that Hoya does not intend to sell Pentax. If they had intended to sell Pentax off, they would have kept it seperate. It would have been very easy for Hoya to simply sell the Pentax stock to Canon or anyone else. Coupla hours for an accountant or lawyer. Divesting a portion of Hoya corporation itself is a much more complex project. Even after the two parties agreed on terms, the actual sepeperation would be long and complicated.
