In 2024 alone, the Federal Circuit affirmed PTAB obviousness calls in eight out of ten cases where patent owners leaned hard on objective indicia. That’s not a fluke; it’s the new normal for nexus fights.
Look, MRI thought they had it locked. Their patents on cooling outdoor displays—U.S. Nos. 8,854,595 and 9,173,322—promised constricted convection, a slick channel of cool air hugging the hot back of the screen. No more bulky fans blasting the whole housing. Genius, right? Samsung called BS in IPR, PTAB agreed, and now the appeals court says: nexus not proven.
How ‘Constricted Convection’ Went from Impressive to Invalid
MRI rolled out the full arsenal. Long-felt need in scorching outdoor displays. Samsung’s own flops at cracking the code. An engineer gushing, “impressive and unique.” Licensing deals. Even accusations of teardown copying. But the Board? Little to no weight. Why? No tight nexus linking that evidence straight to the claims.
Here’s the trap. Track one: prove the product is the claimed invention. MRI’s displays embodied it, sure—but Samsung’s prior art already nipped at the edges. Track two: show indicia tied to what makes the claim inventive. That “constricted convection plate”? Buried in a bigger beast of a display. Judges shrugged: too diluted.
The Board gave all of this evidence “little or no weight.” The Federal Circuit affirmed.
Brutal. MRI’s commercial wins—millions in sales—meant squat without that golden thread.
And.
This isn’t just about flat-screens frying in Phoenix sun. It’s architecture crumbling for any component patent. Think the widget inside your gadget, the algorithm slice in software. Federal Circuit’s dialing up scrutiny, demanding surgical proof your evidence orbits the exact claim language, not the halo of success around it.
Why Does Nexus Hammer Components So Hard?
Start with the why. Obviousness is 35 USC 103’s big bad wolf. Prima facie case from prior art? Easy for challengers. Objective indicia—Graham factors redux—your shield. But post-KSR, courts want ironclad ties. No more ‘substantially the same’ hand-waving.
MRI tried. They mapped features: plate creates channel, air flows posterior. Evidence praised that. Yet PTAB: claims cover too much, evidence too broad. Appeals court nods—nexus fails if product’s fame swamps the specific novelty.
Picture it like this: your killer carburetor patent. Car sells like hotcakes, everyone copies. But if claims are just “improved intake,” nexus slips—success from engine, tires, cupholders? Dilution city.
Samsung bailed on appeal; Director Squires stepped in. Symbolic. Government now guard-dogging PTAB wins, stacking deck against patentees.
Is This the Death Knell for Subcomponent IP?
My take? Bold prediction: by 2030, we’ll see a 40% drop in component patent filings, funneled into trade secrets or design-around thickets. Remember the BlackBerry keyboard wars? Components got eviscerated in smartphones—NTP’s empire shrank to settlements. Same vibe here, but IPR turbocharged.
Critique the spin: Patent owners cry foul, but FedCir’s not wrong. Weak nexus invites sandbagging—claim narrow, evidence wide. Forces sharper drafting upfront. MRI’s patents? Titled generically, claims method-y. Hindsight: bundle into system claims.
But here’s the deep-dive shift. Underlying architecture: PTAB’s become obviousness machine, 85% institution rate lately. Nexus as last defense? It’s booby-trapped for composites. Inventors, pivot—claim the whole shebang, or go secret sauce.
Samsung’s “copying”? Teardowns are fair game pre-patent. Praise from their guy? Anecdote, not industry choir. Long-felt need? Vague without surveys tying to claims.
Worse, displays are commoditized hell. Outdoor LED market hit $10B last year; everyone’s iterating. MRI’s edge? Blunted by nexus.
So, what’s a patent owner do? Antedate with prototypes tied to claims. Hammer licensing language mirroring limitations. Copying? Forensic side-by-side, not vibes.
The Bigger Ripple: From Displays to AI Hardware
Extend it. AI accelerators—those chiplet wonders cooling inference farms. Patent the microchannel? Nexus nightmare if success from tensor cores. Same for edge devices, where thermals make or break.
FedCir’s signaling: no free rides on product glow. Prove the claim caused the kudos. Brutal filter, but weeds weak IP.
Yet optimism flickers. Dissent? None here, but watch for en banc. Or Congress tweaking 103 post-AIA debacle.

Frequently Asked Questions
What is nexus in objective indicia for patents?
Nexus links evidence like sales success directly to your claimed invention’s novelty—not just the product’s overall win.
Why do component patents struggle with PTAB obviousness?
Components get diluted in larger products; proving evidence ties to the subpart (not the whole) is brutally hard under FedCir rules.
Can objective indicia still save a strong prima facie case?
Yes—if nexus is airtight via Track 1 (product=claims) or Track 2 (evidence targets inventive step)—but expect skepticism for subs.
