Dometic’s lawyers strut into federal court, chests puffed, ready to sink Citimarine’s imports. Splash. Federal Circuit just affirmed the ITC’s cold shoulder: no exclusion order for those marine air conditioners.
Here’s the mess. U.S. Patent No. 8,056,351—Dometic’s supposed gem for cramming AC units into tight boat spots. Main body, blower, rotatable assembly. Sounds clever, right? Until prior art called Vector Compact swims in and anticipates half the claims.
Patent Presumption? More Like Patent Pipe Dream
Dometic leaned hard on this Becton Dickinson case—separate claim terms mean separate physical bits. Judge Taranto? Not buying it.
“Dometic relied on a presumption that separately listed claim limitations indicate separate and distinct physical structures, citing Becton, Dickinson & Co. [but] the Federal Circuit rejected this argument.”
Context kills the presumption, folks. Patent spec shows the “assembly” cozying up inside the main body—like that guiding cover perched on the drain pan. Abstract flat-out says “a main body including an assembly.” Boom. Vector’s shroud? Part of the body. No disjointed magic here.
Short version: Dometic’s claims 1-2, 4-5, 7? Dead on anticipation. ITC nailed it, appeals court agrees.
But wait—there’s more flailing. Claims 18-22. Dometic screams about “first axis” construction. ITC says two distinct rotations: one for blower, one for assembly. Court backs ‘em.
Does ‘First Axis’ Mean Two Spins or Just Corporate Spin?
Picture this: confined boat space, AC unit twisting every which way to dodge obstacles. Patent promises dual rotation hubs—independent, structural, functional. Dometic wants a single-axis fudge? Nope.
The spec screams for it. Prosecution history too—Dometic amended to add that “first axis,” beefing up the assembly limit. Can’t collapse ‘em now, even if axes align like shy lovers. “The fact that the blower and duct element are coupled does not eliminate the distinct structural roles of the two modes of rotation,” Taranto writes.
No infringement. No domestic industry tech prong. Citimarine’s gear sails free.
And here’s my hot take—the one nobody’s yelling yet. This reeks of the early 2000s widget wars, where boat and RV makers slung vague hardware patents like confetti. Remember Black & Decker’s power tool spats? Courts started carving ‘em up for sloppy drafting. Dometic’s playing the same tired game. Prediction: ITC’s getting pickier on marine tech—your rotatable doodad better match the drawings pixel-for-pixel, or watch imports flood the deck.
Why Bother with ITC Anyway?
Section 337’s the fast lane for import blocks—no damages, just exclusion. Dometic filed November 2022, targeting Citimarine, Mabru, Shanghai Hopewell, Hehe Industrial. Quick investigation. ALJ summary: Vector anticipates. Commission affirms. Final ID: no dice on the rest.
Dometic’s gripe? ITC botched everything. Court: nah, you’re the ones with mushy claims. Prosecution history disowns your single-axis fantasy.
Punchy truth. Patent trolls—er, enforcers—love presumptions. Courts love spec and history more. Dometic Sweden AB? Should’ve read the fine print before suing.
Look, marine AC isn’t sexy AI or EVs. But the principle? Huge for hardware hustlers. Tight spaces demand tight claims. Dometic’s? Leaky as a bilge pump.
Zoom out wider. ITC’s batting down overbroad patents left and right lately. Stats whisper it: affirmation rates dipping on exclusion orders. Dometic joins the club—Epson, Samsung printer fights got similar slaps. Corporate PR spins this as “vigorous defense.” Please. It’s a loss, dressed in legalese.
Will This Chill Boat AC Innovation?
Nah. Competition heats up. Citimarine’s Vector? Already out there, anticipating claims. Dometic’s tech? Nice, but not bulletproof. Consumers win—cheaper installs, no monopoly markup.
Dometic might appeal en banc or tweak claims in sequels. But Federal Circuit’s clear: context trumps checklists. Drafters, take note—or take a dive.
Dry humor aside, this ruling’s a gut-check for IP shops chasing import bans. You want exclusion? Nail the structure. Or enjoy the splashdown.

Frequently Asked Questions**
What happened in Dometic v. ITC Federal Circuit case? Dometic lost: court affirmed ITC’s no-violation finding on marine AC patent infringement, citing anticipation and bad claim construction.
Does Vector Compact infringe Dometic’s ‘351 patent? No—ITC and Federal Circuit ruled it anticipates key claims and doesn’t hit the rest due to dual-axis requirements.
Why did Federal Circuit reject Dometic’s separate structures argument? Patent spec, figures, and abstract show assembly inside main body—presumption overcome by context.
