The best way to protect your valuable patentable inventions is by careful technical, legal, and business analysis, as well as by providing good explanations. It is important to avoid shortcuts. Ideally, at each step of the process, each patent or patent application should: Clearly show that the invention is useful and patent eligible, Clearly show that the invention isn't obvious in view of prior art,Clearly show how the invention works. The process starts with solidly written patent applications, and continues throughout each patent's life with carefully reasoned supporting documents, and a well-thought-out strategy that takes your business interests, budget, and competitive situation into account.
