One year ago today, the en banc Federal Circuit decided LKQ Corporation v. GM Global Technology Operations LLC, where it overturned the decades-old Rosen-Durling test for obviousness of a design patent for being “improperly rigid.”1 Now, instead of requiring a primary reference to “be ‘basically the same’ as the challenged design claim” and any secondary references to “be ‘so related’ to the primary reference that features in one would suggest application of those features to the other,” courts and examiners apply “a more flexible approach” in line with KSR International Co. v. Teleflex Inc., 550 U.S. 398 (2007) and Graham v. John Deere Co. of Kansas City, 383 U.S. 1 (1996).2 Some feared that the effects of LKQ would be significant.3 But how much has the design patent landscape really changed?

Design Allowance Rate
According to the USPTO’s data that is current through April 2025, the allowance rate for design patent applications has remained in the low to mid-eighties.4

PTAB Institution Rate
During the few years leading up to the LKQ decision, the institution rate for design patents was collectively over 50%.5 But since the LKQ decision, the PTAB has not instituted any post-grant proceedings for design patents, as all three petitions have been denied.6 That being said, given the small sample size, it remains to be seen whether LKQ will have an effect on the difficulty of invalidating design patents post-grant.

District Court Decisions
Similarly, there have not been any district court decisions within the last year invalidating a design patent for being obvious. To the contrary, the United States District Court for the Southern District of Indiana has granted a motion for summary judgment of non-invalidity of design patents despite the defendant arguing that the patents were obvious.7 And the United States District Court for the Northern District of Illinois has found that a defendant did not raise a “substantial question” as to the validity of a design patent in an analysis of whether to grant a preliminary injunction because the defendant did not present evidence or argument as to all of the Graham factors.8 But again, data is limited.

Some courts have signaled that the difference between the Rosen-Durling test and the new obviousness standard is not significant.  For example, the United States District Court for the District of Arizona denied a motion for a new trial when the LKQ decision came out shortly after an $18 million verdict, reasoning that LKQ was not “so disruptive as to consider the jury instructions in this case a miscarriage of justice.”9 On the other hand, other courts have made decisions based on the differences between the old and new tests. For example, the United States District Court for the District of Colorado denied in part a plaintiff’s motion for summary judgment on assignor estoppel and found that “the defendants [we]re not estopped from asserting an obviousness defense” because “[i]n light of the new, more ‘expansive and flexible’ approach to assessing obviousness announced in LKQ, it is now possible that ‘what was valid before is invalid today.’”10

Takeaways
Data from the first year post-LKQ suggests that there may not be significant changes to the allowance rate of design patent applications or the likelihood of the PTAB or district courts invalidating design patents. However, since there are not nearly as many design cases as utility cases, it may be a few more years before some impacts are seen.
