Nearly two decades ago, the Supreme Court’s decision in eBay v. MercExchange quietly reshaped the patent landscape — and not necessarily for the better. The ruling rejected the idea that winning a patent infringement case should automatically lead to an injunction against the infringer. Instead, it required courts to apply a traditional four-factor test to decide if an injunction is appropriate. On the surface, that sounds fair. In practice, though, it has opened the door to a troubling trend: “efficient infringement.”
What Is Efficient Infringement?
Under the eBay framework, infringers can often avoid an injunction, and simply pay damages instead. For patent holders, especially those who don’t manufacture products but license their inventions, removal of the threat of injunction is a loss of bargaining power. In the case of NPEs (Non-Practicing Entities) such as university patent holders, the loss is even worse because their lack of sales means that any assessed money damages might be very slim.
Congress Has Tried to Fix This — With Little Success
Lawmakers proposed the RESTORE Patent Rights Act in both 2024 and 2025 (as H.R. 1574 and S. 708), aiming to make it easier for patent holders to obtain injunctions. But progress has been slow, largely due to the influence of those benefiting from the status quo.
A Potential Shift: Radian v. Samsung
Enter a recent case: Radian Memory Systems v. Samsung. Radian, an NPE, is suing Samsung for patent infringement related to flash memory tech. Samsung argues Radian shouldn’t get an injunction because it doesn’t make or sell products—just licenses them. But here’s where things get interesting: The Department of Justice (DOJ) and the U.S. Patent and Trademark Office (USPTO) jointly filed a Statement of Interest in support of Radian’s request for a preliminary injunction.
What the DOJ and USPTO Are Saying
Their statement doesn’t advocate a specific outcome but urges the court to rethink how irreparable harm is assessed in these cases. They argue that:
- Patent damages are often difficult to calculate, especially for unique technologies.
- Loss of control over licensing terms is a form of irreparable harm.
- The current legal climate makes infringement seem like a better business move than negotiating a license — undermining the whole purpose of patents.
- Denying injunctions by default encourages longer litigation, fewer settlements, and more costs for inventors.
They back this up with case law and academic commentary, emphasizing that even non-practicing entities can suffer real, lasting harm without an injunction.
Why This Matters
This joint DOJ/USPTO statement is significant. It may signal a policy rethink at the federal level about how we treat patent holders—especially small ones—when they try to enforce their rights.
While the eBay decision was part of a broader Supreme Court effort to correct Federal Circuit doctrine (along with decisions like KSR, Bilski, and Myriad), it may have had unintended consequences. Namely, weakening the ability of innovators to protect their work and giving large companies a license to infringe.
The Bottom Line
The DOJ and USPTO aren’t rewriting the rules—yet. But their stance in the Radian case could be a first step toward rebalancing the patent system. Still, lasting change will likely have to come from Congress, no matter how slow or difficult that process may be.
