Password Protected! The Federal Court Revisits TPMs
Savvy content creators and copyright owners often use technical protection measures (also known as “TPMs”) to restrict what users can do with their works (often digital materials). The prohibition against circumventing TPMs is rooted in sections 41 and 41.1 of the Copyright Act, but their fit within the broader Copyright Act is the subject of ongoing debate.

As widely reported by the likes of CBC, the Guardian, the Verge and CNBC, OpenAI has indicated they will “pause” the use of their AI-generated voice after users (and Scarlett Johansson herself) noted the striking similarity to Scarlett Johansson's voice from the film “Her”. This connection may have been intentional, OpenAI’s CEO, Sam Altman, posted a one-word message – “her” – on his social media on the day the AI-generated voice was unveiled.

Innovation in Limbo: A Disappointing Turn in the Benjamin Moore Saga
In our last comment on non-patentable subject matter, we provided our thoughts on the Federal Court of Appeal’s decision in Canada (Attorney General) v Benjamin Moore & Co (the “Benjamin Moore Appeal”). As a top line, this decision was a loss for Canadian innovation. As we discussed in detail, the Federal Court of Appeal missed an opportunity to clarify the law of patentable subject matter, adopt the IPIC framework endorsed by Associate Chief Justice Gagné, and signal to the Canadian Intellectual Property Office (“CIPO”) that its examination practices were out of step with the law. Instead, the Federal Court of Appeal further complicated an already complex area of the law, which will increase the costs of innovators to register their technologies in Canada.

Bars or Bytes? Exploring the Implications of a Track that Drake Might (or Might Not) Have Created
Did Drake respond to an alleged feud with fellow artists, including Kendrick Lamar and Rick Ross? As reported by the LA Times, a track titled ‘Push Ups (Drop and Give Me 50)’ appeared online recently, taking aim at Lamar and several of his recent musical collaborators. However, this track remained unclaimed on any of Drake’s official platforms, causing some to question whether this track was fan-generated using artificial intelligence. This cynicism may be justified: Drake is reportedly no stranger to having to denounce fan-generated songs, and Lamar’s rumoured response was actually the work of artificial intelligence and another rapper.

AI in the Courtroom: The Quest for Legal Precedents
The current landscape is inundated with narratives surrounding artificial intelligence and its intersection with the law. From the New York Time’s lawsuit launched against OpenAI in December 2023, to the BC lawyer reprimanded for citing fake AI-generated cases, to the lying Air Canada chatbot, the legal and mainstream media is full of stories of AI or people using AI running up against traditional legal doctrine and practice. Yet, amidst this surge of AI-related incidents, Canada finds itself grappling with more questions than answers.

Benjamin Moore: An Opportunity Missed
It has been approximately six months since the Federal Court of Appeal’s decision in Canada (Attorney General) v Benjamin Moore & Co (the “Benjamin Moore Appeal”) was released, yet no practice direction has been issued from the Canadian Intellectual Property Office (“CIPO”) to address the decision, and there is no consistency in the way that computer-implemented inventions are being examined. As the patent bar awaits a decision on the leave application to the Supreme Court of Canada, we provide our thoughts on the Federal Court of Appeal’s decision, and the missed opportunity it was.

Don’t Make Me Say It a Fourth Time: Federal Court Weighs in (Again) on Patentable Subject Matter
Associate Chief Justice Gagné’s decision in Benjamin Moore & Co v Attorney General of Canada, 2022 FC 923 (“Benjamin Moore”) marks the second time that the Federal Court has had to weigh in to tell the Commissioner that it was not applying the correct test for patentability of computer-implemented inventions. Unlike past decisions (discussed below), the Court in Benjamin Moore, provided instruction on how the Commissioner ought to assess patentability of such inventions. As a top line, these instructions appear to level the playing field – reducing the artificially high standard that computer-implemented inventions face during patent examination.

Summary adjudication can be enticing. In the right circumstances, it saves the parties time and money. Unsurprisingly, there is a growing trend in Canadian intellectual property litigation to use summary adjudication that we have been actively monitoring (see, e.g., our comments here, here, here, here, here and here).
-
As part of our series on summary adjudication, we previously commented on the Federal Court’s recent use of a summary trial to resolve a patent infringement dispute. The abbreviated procedure of a summary trial addresses many of the Federal Court’s traditional concerns with summary judgment (e.g., lacking live evidence).
