Ownership of intellectual property, including patents , copyrights , and trademarks , may be assigned, but special conditions attach to the assignment of patents and trademarks. In the United States , assignment of a patent is governed by statute , 35 . § 261 . Patent rights are assignable by an "instrument in writing." Title in a patent can also be transferred as a result of other financial transactions, such as a merger or a takeover , or as a result of operation of law, such as in an inheritance process, or in a bankruptcy . An assignment of a patent can be recorded with the United States Patent and Trademark Office . Although such recording is not required, if an assignment is not recorded at the USPTO within three (3) months or prior to a subsequent assignment, the assignment will be void against a subsequent assignee without notice of the earlier, unrecorded assignment.
On August 15, 2016 Canadian Blood Services' new eligibility criteria for transgender people came into effect. This criteria states that transgender donors who have not had lower gender affirming surgery will be asked questions based on their sex assigned at birth. They will be eligible to donate or be deferred based on these criteria. For example, trans women will be asked if they have had had sex with a man in the last 12 months. If the response is yes, they will be deferred for one year after their last sexual contact with a man. And donors who have had lower gender affirming surgery will be deferred from donating blood for one year after their surgery. After that year, these donors will be screened in their affirmed gender.
