Western Digital’s lawyers hit ‘file’ on a reexam request, 48 hours after a PTAB gut-punch on a sister patent.
Ex parte reexamination. That’s the dirty word buzzing through patent halls right now—the fallback weapon for challengers dodging IPR estoppel like pros. USPTO’s latest move, a pre-order SNQ procedure, sounds tough. But it’s a half-measure in a war where the bad guys just repackage their losers and try again. And here’s the kicker: it won’t touch the real abuse.
“While [the Pre-order Procedure Regarding SNQ] is an important first step and will likely prevent the institution of some—perhaps many—ex parte reexaminations, the real mischief associated with repackaging failed IPRs as reexaminations is not SNQ related.”
That quote nails it. Straight from the trenches. USPTO dropped this in the Official Gazette, patting itself on the back. But skeptics—and anyone who’s watched PTAB poker—know better.
Western Digital’s 48-Hour Pivot: Desperation or Checkmate?
Back to the scene. September 2024: Western Digital files IPR on IP Bridge’s ‘909 patent. Full trial. Oral hearing January 2026, bundled with siblings like ‘134. Coordinated assault, check.
March 27, 2026. FWD drops on ‘134—mixed bag, some claims die, others limp on. Signal received: this panel isn’t your patsy. Expected ‘909 decision? Looming. Solution? Boom. Reexam request on ‘909 claims 5-6, 9-20. Art? Kishi and Parkin. Old news. Kishi rejected a child app pre-IPR. Parkin? Prosecution staple.
Why now? Timing’s everything. File pre-FWD, dodge estoppel under 35 U.S.C. § 315(e). Can’t raise what you “reasonably could have” if the IPR hasn’t closed. Sneaky. Brilliant. Infuriating.
Short version: it’s gaming the system. Hard.
And PTAB? Watching parallel tracks collide. Patent owners sweat, victories turn to vapor.
Why Does USPTO’s SNQ Fix Miss the Mark?
USPTO’s new toy: patent owners challenge SNQ before institution. Good start. Blocks some reexams cold.
But—crucial but—the procedure mandates SNQ first, discretionary factors later. Repackaged IPR arguments? They sail through SNQ if twisted just so. No estoppel shield yet. Challengers laugh.
Think historical parallel—my unique twist: this echoes pre-AIA patent troll fiestas. Serial lawsuits, forum-shopping hell. Congress birthed IPRs to kill that. Now? Reexams as troll 2.0. Without fixes, we’re looping back to 2010 chaos, just with fancier acronyms.
USPTO’s PR spin? “Important first step.” Cute. It’s a speed bump on a loophole highway.
Look. Patent owners win IPR? Provisional. Challenger reroutes to CRU, reboots. Structural failure, not feature.
Is This the New Normal for Patent Wars?
Aggressive tactics? Norm now. Discretionary denials spike—petitioners pivot to reexams. Post-denial, post-hearing, pre-FWD. All fair game.
Western Digital’s play: textbook. Why skip Kishi/Parkin in IPR? Estoppel fear. Save ‘em for reexam purity.
Bold prediction: without estoppel tweaks or reexam reforms, expect 2x reexam filings by 2028. PTAB dockets swell. Costs skyrocket. Innovation? Chilled.
Here’s the thing—USPTO could close this. Mandate estoppel across proceedings. Or kill parallel filings mid-IPR. Won’t happen fast. Too many Big Tech petitioners love the dodge.
Dry humor alert: it’s like banning guns but handing out slingshots. Effective?
And patent owners? Fight back. Argue estoppel anyway. Crowd dockets. Chaos reigns.
But wait—there’s more maneuvering potential. What if challengers file reexams pre-IPR? Stack ‘em. Overload.
Single sentence warning: this erodes PTAB’s bite.
USPTO’s watching cases like Western Digital’s. Will they act? Or let the hole gape?
The Bigger Picture: Estoppel’s Fragile Web
§315(e) bars grounds “raised or reasonably could have raised.” Timing exploit: pre-FWD filing. Courts might buy it—or not. Unsettled law, ripe for abuse.
IP Bridge fights. Western Digital pushes. USPTO referees, half-heartedly.
Corporate hype from petitioners? “New art!” Please. Conceded oldies.
Wander a sec: remember Alice? Killed software patents overnight. Now reexams as life support. Ironic.

Frequently Asked Questions
What is ex parte reexamination?
Quick requester-triggered USPTO review for new patentability questions. No petitioner response rights—owner fights solo. Cheaper than IPR, endless potential.
How does IPR estoppel apply to reexams?
Blocks grounds from IPR in later proceedings post-FWD. Loophole: file reexam before FWD, claim no estoppel trigger. Contested, but working so far.
Will USPTO close the reexam loophole?
Maybe someday. SNQ pre-order’s a nudge. Needs estoppel expansion or filing bans for real fix. Don’t hold breath.
