As it turns out, there are as many origin stories for barbecue as there are spellings of the word on neon signs. These explanations range from a linguistic attempt to connect barbecue to boucan (also French) to a tall tale tracing barbecue to a Texas rancher who happened to brand the initials B.Q. on his livestock.
Patent protection usually ends when the patent expires. Here are the expiration dates: For all utility patents filed before June 8, 1995, the patent term is 20 years from date of filing, or 17 years from date of issuance, whichever period is longer.
Copyright protection always expires at the end of the calendar year of the year itâs set to expire. In other words, the last day of copyright protection for any work is December 31. For example, if an author of a work died on June 1, 2000, protection of the works would continue through December 31, 2070.
