Intellectual Property Law in Canada – Patents
In Canada, the guidelines issued by the Canadian Intellectual Property Office stipulate that to obtain a patent involving software, the patent claims must focus on:1
“an act or series of acts performed by some physical agent upon some physical object and producing in such object some change either of character or condition” and that that physical agent: “must produce an essentially economic result in relation to trade, industry or commerce.”
Software protection in Canada can be obtained in the form of method claims, which define a series of operations that take place within the hardware of a computer. Infringement includes the use, manufacture, and sale of software media. Anyone who infringes on the patent must be in possession of operating hardware which incorporates the software in order to be guilty of infringement. As such, substantial protection for Canadian software inventions is available, since this hardware limitation is not overbearing or excessively restrictive.
Most recently in Canada, the Federal Court of Appeal made an important decision 2 in The Attorney General of Canada and the Commissioner of Patents vs. Amazon.com Inc that reversed the ruling by the Trial Decision that a patent could issue in Canada for Amazon’s “one click” method of enabling online purchasing. The case was sent back to the Commissioner for further review based on principles provided by the appeal court. While addressing a “business method patent”, this decision includes statements that relate to software. Foremost are the following points:
- It is not essential that patentable subject matter must be scientific or technological in nature (except insofar as it distinguishes such patents from the fine arts or works of art that are inventive only in an artistic sense);
- There is no basis within the law to suggest that a business method cannot be patentable subject matter in Canada; and
- A patentable art must cause a change in the character or condition of a physical object.
Intellectual Property Law in the United States – Patents
Prior to the United States Supreme Court decision in Bilski v. Kappos, 130 S. Ct. 3218 (2010),3 the US Court of Appeals for the Federal Circuit had attempted to establish a rule that would limit both software and business method patents. The proposed rule would ensure that all patent claims had to be a) tied to a particular machine or apparatus, or b) transform a particular article into a different state or thing. Essentially, it was proposed that patents should only address either a machine element or something that would effect a transformation in something tangible. This rule was to apply in conjunction with the novel feature requirement (read more about the novelty requirement here) and extended to both method and apparatus claims. The presence of software in such a claim would not defeat the claim’s validity if the proposed test and other requirements for patenting beyond novelty–such as adequate disclosure–were met.
In its 2010 Bilski decision, the Supreme Court rejected the notion that the machine-or-transformation test could serve as the exclusive test of the patentable subject matter of a newly invented process. In the new rubric, the machine-or-transformation test offers only an important clue. Instead, the Supreme Court seemed to suggest that patents could issue as long as they did not attempt to monopolize an abstract theorem. This guideline has been highly unsatisfactory so far.
The result is that there is a continued state of uncertainty as to the full extent to which software can be patented in the United States. However, if the machine-or-transformation test is met, a patent can likely be issued for what is essentially a software invention.
The Bottom Line: Avoid Complacency
Given the cluster of issues surrounding whether or not patents can be obtained for inventions that are essentially SR&ED eligible software, it can be difficult to understand what exactly falls under the umbrella of IP protection. However, there is certainly scope for patenting software in the proper context. In the case of valuable advances, it may be worth the cost of investing in a patent application because the jurisprudence is still in flux.
In previous articles, the importance of a) understanding the scope of patent and copyright protection for software inventions, and b) conducting market research before submitting your patent claim to ensure that your claim meets the “novelty requirement” were both stressed. As with reducing the risk of a SR&ED review, the key to maximizing your time and resources when it comes to IP protection for software inventions lies in avoiding complacency.
Here are some conclusions that can be taken away from our Software Patents and SR&ED series:
1) Find out if copyright protection or patenting will be useful for your software invention.
Depending on the specifics of your particular invention, IP protection may or may not add value to your invention. Useful IP protection gives you a competitive edge over inventors with similar software, as it blocks competitors from attempting to market products that are highly similar to yours.
2) There is no point obtaining a patent if there are other ways to achieve the same result.
If you have a treasure map showing a single path through a forest on a remote island that leads to buried treasure, then this map possesses an obvious value. The map will have far less value if others are able to produce their own distinct maps showing alternate paths to the treasure. The same can be said for software patenting.
3) Do the research.
Before investing any money in the prospect of obtaining a software patent, a sober evaluation should be made of the marketplace to determine whether the prospective patent will have any significant blocking power which will give it commercial value.
We hope you’ve taken away some useful advice from this series about the value-adding potential of software patenting and copyright protection. While it may not be of use to every inventor, it is worth taking the time to consider the benefits and drawbacks.
