Improve the patent infringement of the original patent

Mainly depends on whether the revision and improvement have reached a certain level and whether your patent scope is well written:

1. If you can apply for a new patent, and it can't form a parent patent with your patent, then there is no infringement! If you form a parent-child patent relationship with your patent and apply for a patent, it constitutes a cross-licensing relationship; Not applying for a patent is infringement!

If it doesn't reach the level where you can apply for a new patent, it's infringement!

Legal and technical issues are intertwined, so it is recommended to consult a patent agent or lawyer.
