What is Patent Drafting?
The complete specification decides what your patent actually protects. Claims that are too broad get rejected; claims that are too narrow are easy to design around.
Our registered patent agents draft the description, drawings, claims and abstract in the format the Indian Patent Office expects, working closely with your inventors.
