1. What are the characteristics of the British patent system? The British Patent and Trademark Office is responsible for accepting, examining, and approving patent and trademark applications. Since then, it has been revised, supplemented and improved many times, forming a set of detailed legislation covering three types of patents: invention patents, appearance patents and plant patents. Many important provisions are directly included in the Patent Law, including changing the non-public review system to an early public delayed review system and ensuring the patent protection period for inventors. The signing of the Act marked an important milestone in the history of the patent system and the UK Patent and Trademark Office. There are three types of patent protection in the UK: invention patents, plant patents and appearance patents. The UK patent system has some unique features. For example: first-to-invent system: The UK implements a "first-to-invent system" instead of the first-to-application system implemented in most countries in the world. "First to invent" means that the patent application must be filed by the inventor, and the inventor can transfer the application right at the same time or after filing the patent application. Therefore, the right holders that often appear in British patent documents are the inventor and the assignee. 2. What materials are needed to apply for British trademark registration? The documents that need to be submitted when filing an invention patent application include: transmittal form or transmittal letter, fee payment status, application data page, description (at least one claim), drawings (if necessary), An oath or declaration signed by the inventor, a power of attorney, and an information disclosure statement (IDS). In the UK, patent applications can be filed with non-English specifications. An affidavit or declaration may be made later, and any inventor must sign the oath or declaration certifying that he or she is the original inventor of the invention described. The oath or declaration is generally signed by the inventor himself or by someone authorized by law to sign on his behalf. The oath must be sworn and signed before a notary or similar official. The declaration does not have to be signed by a notary or similar official, it can be used in lieu of an oath and is therefore recommended. When submitting a continuation application or provisional application, a copy of the oath or declaration from the earlier application can be used. If priority is requested, the certificate document can be submitted before the authorization registration procedure is carried out. To sum up, many large domestic companies are now developing abroad. For example, to obtain a patent in the UK, you need to apply for registration. The British patent policy is a first-to-invent system, which is different from other countries. That is to say, a patent application must be filed by the inventor first, and the British Patent Office will review the application materials after receiving them, and then issue a patent license.
