Hello, although your patent name indicates that it is applied to street lamps, if you directly copy this technical means to ceiling lamps without creative labor, it is generally believed that your patent right may be infringed, but whether the technical means adopted by the other party falls within the scope of your patent protection depends on whether it is infringed. In the judgment of patent infringement, there are: the principle of universal application and the principle of equivalence. To put it simply, if the claim of your patent document is disclosed: A+B+C+D, four technical features, if the other party adopts A+B+C, it is not infringing, while if it is A+B+C+D or A+B+C+D+E, it is infringing; Or the other party uses A+B+C+E, but E and D can have the same technical effect, and E can be directly thought of by ordinary technicians in this field without creative labor, or it is an equivalent replacement of ordinary technical means, which is also regarded as infringement.
Typical case: In 50 typical intellectual property cases in 2065438+2008, there was a patent dispute over the utility model of smart blackboard. Because the patentee claimed in the claim that his smart blackboard used inorganic glass and his competitor used plexiglass, the technical characteristics were different, and the competitor's products did not fall within the scope of patent protection, so the plaintiff lost the case.
In view of your situation, it is recommended to find a professional intellectual property lawyer to help you analyze, because they are much more reliable in handling patent disputes.
Hope to adopt.
