A: You need to search whether the other party is registered effectively. If their application for registration is not approved, it is not infringement. However, if someone successfully registers and is still in the protection period, your behavior belongs to infringement.
I don't have the registration number of the industrial and commercial bureau now. They said they had a patent for more than eight years. I want to ask what they registered.
a: the longest period of patent protection is 2 years. most of the patents that have been in the past eight years have expired, and there may be no infringement.
patent, brand or trademark?
a: it is estimated that the other party registered a trademark. Trademark registration is protected for 1 years at a time. If the other party fails to renew it in time, it will be invalid in more than 9 years. If it is renewed, it may still be within the validity period. Suggest a trademark search.
what are the legal provisions for those registered with the same or similar names?
a: the same name or similar name cannot be registered on the same kind of goods or services. That is to say, if there is a similar prior registration, your trademark cannot be approved. Moreover, your use of its trademark without the consent of the trademark owner will be regarded as infringement.
