Should I Patent my Invention? | Canadian Patent Filing & Registration

A self-assessment checklist


Deciding whether to patent an invention is one of the most difficult decisions management of a business can face.  On the one hand, patent applications are expensive and consume scarce capital and management time.  On the other hand, patents may represent the “crown jewels” of a business and there is a common perception that patents are crucial for raising investment capital.

This tool is not a substitute for legal advice, nor expected to produce definitive answers.  Management is an art, not a science, so not tool can produce “the answer”.  It is intended as a rough guide to help management manage.

In this tool, an “invention” is the novel feature, method, process or combination.  It is not the product or service that incorporates (or ‘embodies’)  – and goes beyond – the invention.

The factors that influence whether investing in a patent is likely to be worthwhile include:

The costs of acquiring patent rights:

  • How difficult will it be to draft and prosecute the patent?
  • In how many countries will you need to protect your invention?
  • How difficult will it be for you to bear these costs?

The costs of enforcement:

  • How difficult will it be to determine if someone is infringing your patent?
  • Can you, or a purchaser of the patent, afford to sue?
  • Will your judgement be enforceable and stop infringement?

Monetizing.  Patents only pay off if they generate profit.  This can come from any or all of increased revenue, increased gross margins, or the sale of the business or IP.

  • What is the incremental gross margin from the patent: does the invention generate incremental revenue and/or take market share from products/services without it?
  • Will it be possible to sell or license the IP or is someone likely to pay more for the business with the IP than without?

 How to interpret the results of the scorecard below.

Total between:

0-15:        Patenting may not be a wise use of funds.

16-30:      Consider patenting and the alternatives.  Watch your costs prudently.

>30:      Consult a patent agent promptly and keep the invention secret.
