Sorry for the dumb questions but as an engineer I am trying to file a patent myself.
I was advised to copy the existing patent that is very similar to mine and start by modifying it for my own idea.
My question is:
When writing an independent claim, will it be considered as a valid new patent if I slightly modify it like adding a new component? My background is academia where using the same expression can be considered plagiarism but I heard it is not the case in patent writing. Is it true?
E.g Claim 1 of the existing patent is consists of an image sensor and a lens whereas mine has one more component in the middle beam splitter. So, if I use all the words and descriptions of the existing one and add a new description on the new component or slightly modify the original sentence, will it be okay?
