Zero tolerance for sloppy claims. The U.S. Court of Appeals for the Federal Circuit dropped a ruling Thursday that should make patent trolls sweat—affirming non-infringement for Hulu in a streaming patent spat with Sound View Innovations.
That’s right: CAFC affirms non-infringement ruling because Hulu’s products don’t dance the exact step sequence demanded by claim 16 of U.S. Patent No. 6,708,213. Judge Chen’s opinion? Crystal clear on grammar trumping tech hacks.
Hulu. Lucky again.
This isn’t some footnote case. It’s precedential. Remanded once before in 2022 after the CAFC nixed a broad ‘buffer’ construction—can’t mean just any ‘cache,’ folks. Back to district court, which tried a narrower take: ‘short term storage associated with said requested SM object.’ Hulu still won summary judgment. Sound View appealed. CAFC? Splits the baby—wrong on buffer, right on order. Affirmed.
The buffer fight? District court called it a ‘specialized buffer dedicated to a single SM object.’ Hulu’s gear? General-purpose. No dice. But CAFC smacked that down. ‘Nothing in the claim language describes the buffer as a specialized buffer,’ they wrote. Intrinsic evidence doesn’t demand exclusivity. Sound View dodged a bullet there—but not the big one.
Why Did Grammar Seal Hulu’s Victory?
Enter the killer quote:
“Both the grammar and logic of claim 16 require the first limitation to be performed before the second.”
Boom. Claim 16: First, receive a request for a streaming media (SM) object at a helper server. Then, allocate a buffer to cache at least a portion of said requested SM object. That ‘said requested’? Past participle magic. It screams antecedent—request happens first, or the whole thing collapses like a house of cards.
Hulu’s accused products? They cache first, request later. Or something out of whack. Doesn’t matter—sequence broken. Sound View whined: No explicit order! Steps flexible! CAFC: Nope. Cites Mformation: Logic or grammar mandates it. Here, ‘requested’ isn’t fluff—it’s a status post-receipt. Second step leans on the first. Implicit dependency? Ironclad.
And here’s my hot take, absent from the opinion: This echoes the dot-com bust era, when broadband patents got shredded for ignoring real-world packet flows. Sound View (read: patent assertion entity, aka troll) thought they could vague-up method claims for easy licensing. Wrong decade. With Alice lurking, courts crave precision—or else.
Predict this: More summary judgments for streamers like Netflix, Disney+. Trolls will scramble to rewrite portfolios.
District court’s buffer flub? CAFC fixed it fast. Ordinary meaning: ‘temporary storage for data being sent or received.’ No ‘association transforms’ nonsense. Hulu’s general buffers? Fine. But order? Unforgivable.
Sound View pushed: Any order works! Specs allow it! CAFC: Specs don’t override claim logic. Functional ties bind steps. No free-for-all.
Does Claim Step Order Still Trap Tech Giants in 2024?
Short answer: Hell yes. Patents aren’t choose-your-own-adventure books. Especially in streaming, where CDNs and edge caches already scramble sequences for speed. Hulu’s win? Vindication for accused infringers tired of ‘substantial compliance’ BS.
Think about it. Streaming patents exploded post-YouTube. Trolls hoarded ‘em, shaking down Big Tech. But courts? Weaponizing grammar now. That ‘said requested’ phrase? Buried in thousands of claims. Lawyers, dust off your Strunk & White.
Corporate spin from Sound View? Silent so far. But expect appeals or new suits with reordered language. Hulu’s PR? Muted victory lap. Smart—they know trolls multiply.
Dry humor aside: Imagine defending infringement where your buffer parties before the invite arrives. CAFC: Party foul.
The remand history? Comedy of errors. 2022 CAFC vacates broad non-infringement. District tightens, still wins for Hulu. Round two appeal: CAFC tweaks buffer, upholds order. Efficient? Barely. But precedential punch lands.
Broader ripple? Method claims everywhere—AI training pipelines, blockchain txns—face step scrutiny. If logic demands order, no vitiation arguments save you.
What Hulu’s Win Means for Patent Trolls
Trolls like Sound View? They’re the cockroaches of IP—survive anything. But this? Starves ‘em. General-purpose tech (every cloud server ever) sidesteps ‘specialized’ reads. Order kills the rest.
Bold prediction: CAFC doubles down next year. PTAB follows. Streaming patent values plummet 20-30%. Investors, sell.
Hulu? Stock uptick? Meh. But legal fees saved: Millions.
Wrapping the tech: Helper servers (HSs), SM objects, buffers—’90s lingo for modern CDNs. Patent from 2002-ish. Feels quaint against HLS, DASH. Yet trolls cling.
CAFC’s logic? Timeless. Grammar doesn’t age.

What does the CAFC Hulu decision mean for streaming patents?
It mandates strict step order in method claims—receive request before caching the ‘requested’ object. Broken sequence? No infringement.
Does claim grammar override software flexibility in patents?
Yes, per CAFC: Logic and grammar trump. No rearranging steps unless spec demands it.
Will this CAFC ruling affect other Hulu patent cases?
Likely—precedential weight strengthens non-infringement defenses on order grounds.
