What to do next
Who this affects
Inventors and startups filing for the first time, companies whose in-house filings have stalled, businesses whose application was abandoned by a previous agent, and applicants pursuing the same invention in several countries where one office has objected and others have not.
Identify the ground, then the deadline
Objections generally fall into a few categories: prior art defeating novelty, obviousness over a combination of references, subject matter not patentable, insufficient disclosure, or claim clarity and formality. Each has a different response. The deadline is stated in the office action and extensions must themselves be requested in time.
Choose the response that fits the objection
For prior art, argue the cited reference does not disclose an element, or amend the claims to distinguish it - accepting that amendments narrow what you can later enforce. For obviousness, argue the combination would not have been obvious and point to unexpected results. For subject matter, particularly software, reframe around the technical problem solved rather than the abstract idea.
Consider whether the claims are worth having
Narrowing a claim to secure allowance can leave a patent that is granted but easy to design around. A patent agent will tell you when the remaining scope is not worth the maintenance fees - and that is sometimes the most valuable advice available. A trade secret may protect the invention better if it is not visible in the product.
What to prepare
The application as filed, every office action and prior response, the cited prior art references, your own knowledge of the field and any prior art you are aware of, test data or results showing unexpected advantages, and the commercial importance of the specific claims under objection.
Possible legal pathways
A written response with argument, amendment of the claims, an examiner interview where available, a divisional or continuation application preserving the original filing date for other aspects, appeal to the patent appeal board, or in Canada judicial review in the Federal Court. Abandoning deliberately is also a legitimate decision when the remaining scope has no commercial value.
Frequently asked questions
Is a rejection final?
Usually not. Most applications receive at least one office action, and many are resolved by argument or amendment. A final rejection has its own further routes including appeal.
What if I missed the deadline?
The application is generally abandoned. Reinstatement is possible in limited circumstances and within a further window, but refiling means losing your original filing date - which matters greatly if anyone else filed in the meantime.
Can I appeal a refusal?
Yes, to the patent appeal board, and in Canada onward to the Federal Court. Appeals are slower and costlier than amendment, so they suit cases where the claim scope genuinely matters.
Why was my software application refused?
Software is patentable only where it produces a practical technical result rather than automating a known process. The response usually reframes the claims around the technical problem being solved.
Should I just narrow the claims to get it granted?
Only if what remains has commercial value. A granted patent that is trivially designed around costs maintenance fees and protects nothing.
Does a refusal in one country affect others?
Not directly - patents are examined nationally and outcomes differ. But cited prior art is often reused, so a refusal elsewhere is a useful signal about what you will face.
