Used properly, Open Source Software (OSS) is an excellent tool. It saves your business time and money, enables interoperability of product platforms, and developers love it. But used improperly, it can be financially and operationally devastating. For example, the statutory damages for failure to properly adhere to the OSS copyright notice can be up to $150,000 per act of infringement. Those damages can quickly add up to serious consequences, whether preventing a sale or merger of your company or the destruction of the value of the affected products. Another serious risk is that once OSS is used in your code base and deployed in distributed products, if your tech teams are not monitoring and applying bug fixes, known vulnerabilities become Trojan horses of opportunity for bad actors. The good news is that protecting your company from these types of risks is rather simple. We have outlined below key steps and processes in-house counsel should take to work with your business stakeholders to mitigate these risks.

Last week, the Federal Circuit issued a decision holding that parties can contractually bargain away their rights to file petitions for Inter Partes Review (“IPR”) at the Patent Trial and Appeals Board (“the Board”). This precedential case is the first to hold that a forum selection clause can forfeit the right to challenge a patent’s validity by IPR. The takeaway from this case is that when entering into any type of patent related agreement, be careful to ensure that your right to file IPR petitions is not stripped away, particularly by way of a forum selection clause which is “prima facie valid and should be enforced” in the words of the Federal Circuit.

We previously discussed which portions of an artificial intelligence/machine-learning (“AI/ML”) platform can be patented.  Under what circumstances, however, is it best to keep at least a portion of the platform a trade secret? And what are some best practices for protecting trade secrets? In this post, we explore important considerations and essential business practices to keep in mind when working to protect the value of trade secrets specific to AI/ML platforms, as well as the pros and cons of trade secret versus patent protection.

Intellectual Property Viewpoints Thumbnail
The U.S. International Trade Commission (the “ITC”), in an important new opinion, recently extended a series of final determinations that complainants had satisfied the “economic prong” of Section 337’s domestic injury requirement.  This decision reinforces the Commission’s critical role in defending U.S. intellectual property rights and bodes well for patent owners.  In Certain Percussive Massage Devices, Inv. No. 337-TA-1206, the Commission found that complainant Hyperice Inc. proved it had “significant” domestic industry investments in labor, notwithstanding that all of the domestic industry devices were manufactured overseas.  Indeed, thus far in 2022, the Commission has found the economic prong of the domestic industry requirement satisfied in all four public final determinations.  In 2021 and 2022 combined, the Commission found the economic prong of the domestic industry requirement satisfied in 80% of all patent-based investigations that resolved on the merits, demonstrating that Complainants with well-organized, substantiated domestic industry cases continue to meet with success at the ITC.
