IP rights are created by law, and continue to exist even if the person who last owned them stops existing.
What about rights created under private contracts?
Say I granted my former employer the exclusive right to pop round and inspect my garage, with reasonable notice, and carry off anything with a company asset tag, as part of a severance deal.
Now, say the company in question dissolves. It isn't straight up bought (in which case the buyer would own all its rights). It is dis-incorporated, personal property, inventory, and patents are sold off, and the proceeds are distributed to shareholders.
To whom, if anyone, do I now owe the right to inspect my garage? Can that sort of generic contractual right be sold or transferred "by default", without any special language in the contract to enable it? If the company made no attempt to specifically sell it, is it destroyed or does it become jointly owned by the shareholders somehow?
