The JOOLA Pickleball Lawsuit, Decoded: What the Patents Actually Claim
The lawsuit is widely read as a fight over "Gen 3" paddles or banned shapes. The claims say otherwise. Working from the patent text and a set of paddles he's cut open, Johnkew traces the case to one construction detail present in every accused paddle — and notes the whole thing may come down to prior art.

The popular take — that the lawsuit is about 'Gen 3' paddles or 'diving board' shapes — misses the point. As a patent attorney told him: only the claims matter, and the claims describe a specific construction.
JOOLA filed an ITC complaint (Section 337, aimed at blocking imports, not just damages) against 11 companies, on two patents: 826 (the key one) and 891.
Patent 826 requires a layered build: a core, then a gap with TWO fillers — an inner foam (e.g., an EVA 'horseshoe') and an outer hollow carbon-fiber 'frame'/'sushi roll' that can be filled with anything, even air. Every accused paddle shares it.
What's NOT accused: paddles with a single filler running to the edge (no frame), like the Selkirk Era — and none of it hinges on whether the core 'floats.' Patent 891 is separate: internal core gaps, likely protecting the Pro 4 neck-foam inserts.
The wildcard that could decide the case: prior art — if defendants show the construction was already known, used, published, or obvious, the patents can be invalidated.
01 · The lawsuit isn't what you think
Read the claims, not the headlines
He sets the caveat first: he's an engineer, not an attorney, and this isn't legal advice. The one piece of advice he got from a patent attorney organizes the whole video — only the claims matter. And the claims don't describe what most people think the suit is about.

Everybody thinks this JOOLA lawsuit is about Gen 3 paddles, but the actual patents say something completely different.— Johnkew

The paddle generations, sliced open
He's cut these paddles open for years, so he walks the actual cross-sections. Gen 1 (the original Franklin Ben Johns) is one slab of honeycomb polypropylene, edge to edge — no foam, no fillers. Gen 2 adds the "sushi roll" around the perimeter: a carbon-fiber tube filled with expanding edge foam, expanded in the oven so it fills the gap.
The cross-section is the point: a plain honeycomb core (Gen 1) vs. the same core ringed by a foam-filled frame (Gen 2).00:02:37
03 · Patent 826
The two-filler "sushi roll" structure
From the center out, 826 describes a core, then a gap filled with material, then an outer frame. What Gen 3 adds is a second filler in that gap — a white EVA-foam "horseshoe" between the core and the frame. The claimed structure is core → first filler → second filler (the hollow frame).
The layers on a Gen 3: honeycomb core, the EVA-foam horseshoe, then the carbon-fiber frame.00:03:37
What the claim does and doesn't requireBoth layers of filler have to be present to match the claims. The frame itself doesn't have to contain anything in particular — the expanding edge foam is most common, but even pressurized air is covered. And the core needn't be honeycomb; per the claim it "can be anything."
04 · What's in — and what's out
Single filler ≠ infringement
Every paddle in the complaint shares the two-filler pattern. Paddles with a single filler running to the edge — no frame — don't appear.
The Selkirk Era has one softer EVA layer running from the core to the edge, with no expanding-foam frame outside it — a different structure from the accused paddles.00:04:37
He's also explicit that none of this turns on whether the core is "fully floating," which he flags as a common misconception.
05 · Patent 891
The core gaps and the neck-foam inserts
891 is a separate claim, and he calls it the more confusing of the two. Instead of the core-to-edge layering, it's about modifying the inside of the core — cutting gaps and either filling them or leaving them empty. His read, which he hedges as a read: it's protecting the Pro 4's neck-foam inserts (later branded "TFP foam inserts"), and that depends on a specific ordering — the expanding edge foam tucking inside, between the core and the neck foam, rather than outside it.
The 891 figure (red arrows added): the sequence of foams around the neck is what he thinks the patent is protecting.00:08:23
06 · The wildcard
Prior art could undo it all
A patent that's valid on paper can still be invalidated. If the defendants show the construction was already known, used, published, or obvious from existing technology — prior art — the claims can be knocked out.
Prior art is the factor he thinks could ultimately decide whether JOOLA's patents are enforceable at all.00:09:28
Even if JOOLA's patents are valid on paper, they can still be invalidated by the defendants if they can prove that the technology already existed.— Johnkew
