Stage 2: Examination

• Novelty: Is your invention truly new and not already publicly known?
• Non-obviousness: Does it differ significantly from existing inventions, requiring an "inventive step"?
• Utility: Does it have a practical use and produce a tangible result?

The examiner may raise concerns or objections based on identified prior art that are relevant to your invention, requiring you or your attorney to respond with arguments, amendments, or additional evidence to address these concerns.

Stage 3: Communication & Negotiation

This stage involves back-and-forth communication with the examiner. You might need to clarify claims, modify drawings, or cite relevant references to convince them of your invention's patentability.

Negotiations and amendments may be necessary to narrow the scope of your claims while ensuring they adequately protect your invention.

Stage 4: Allowance & Issuance

If the examiner is satisfied that your invention meets all the requirements, they will allow the application and grant you a patent.

Stage 5: Post-Grant Maintenance:

To maintain your patent rights, you need to pay maintenance fees periodically throughout the 20-year lifespan of the patent.

Patent prosecution can be a complex and time-consuming process, especially for complex inventions. It is highly recommended to seek guidance from a patent expert or a patent attorney familiar with your specific technology area. Experts can help you navigate the process and increase your chances of success.
