BitHarmony v. Warner Bros. Discovery — Video-Transcoding Patents Survive Section 101 at Pleading Stage, but Pre-Suit Knowledge and Direct Infringement Allegations Dismissed

Background

BitHarmony LLC sued Warner Bros. Discovery and three affiliates for infringing four patents on video processing technology: U.S. Patent Nos. 7,707,485, 9,258,605, 9,641,322 and 9,826,259. The patents address content-based “transrating” (adjusting bit rate or resolution based on program content), program-type-based bit rate limits, container-agnostic decryption of partially encrypted video streams, and managed degradation of video streams. BitHarmony says defendants’ streaming platforms (for example HBO, HBO Max and discovery+) use backend transcoding processes that infringe. After defendants moved to dismiss, BitHarmony filed an amended complaint with almost 70 more pages of allegations and a 71-page expert declaration. Defendants moved again, arguing that (1) pre-suit knowledge was inadequately pleaded, undermining induced infringement and willfulness claims; (2) the claims of three patents are ineligible under 35 U.S.C. § 101; and (3) direct infringement was not pleaded against any specific defendant or product. A court in the Eastern District of Virginia had made eligibility rulings on some related claims in a separate case against another defendant.

The Court’s Holding

Judge William C. Bryson of the Federal Circuit, sitting by designation, granted the motion in part and denied it in part, dismissing the amended complaint without prejudice and with leave to file a second amended complaint within 10 days.

Pre-suit knowledge (dismissed). BitHarmony tried to show that the defendants or their predecessors knew of the patents before suit through allegations about its predecessor’s patent portfolio valuation and licensing outreach, participation in an industry consortium and an International Trade Commission investigation involving a different company. The court held these allegations required “layers of inferences” and showed at most industry participation or contact with other companies, not knowledge of the particular patents. Press releases were not alleged to list the asserted patents or to have reached defendants, an allegation of direct contact was pleaded only on information and belief and qualified as speculation, and awareness of a patent application generally does not establish knowledge of the later-issued patent. Willful blindness requires subjective belief in a high probability that a fact exists plus deliberate steps to avoid learning it, and allegations that the company lacked patent-monitoring policies fell short. Infringement and willfulness theories that depend on pre-suit knowledge were therefore dismissed. But the court held, as it has before, that the filing of a complaint can supply post-suit knowledge where an amended complaint is pleaded with knowledge of the patents, so that part of the motion was denied.

Section 101 (motion denied). Defendants argued that representative claims of the ‘485, ‘605 and ‘322 patents are directed to abstract ideas, such as classifying data and applying generic rules. The court declined to apply collateral estoppel based on the Virginia ruling, which defendants addressed in two sentences, because non-mutual estoppel requires careful consideration of whether there was a full and fair opportunity to litigate and a final judgment, and in any event would not apply to every claim. It declined to resolve Alice step one on defendants’ cursory arguments, and held that even assuming the claims were abstract, they could not be dismissed at Alice step two because the amended complaint and expert declaration included plausible, specific factual allegations that the claimed combinations were not well-understood, routine or conventional, and that they improved the functioning of video transcoding or decryption hardware (for example, by replacing “content-blind” transcoding or container-level decryption). Under Federal Circuit precedent such as Aatrix and Cellspin, those fact questions cannot be resolved against the patentee on a motion to dismiss. The court noted that the Virginia court had itself found an inventive concept sufficiently alleged for claim 19 of the ‘605 patent, making defendants’ reliance on it “perplexing.” It did not decide whether the claims are representative of the rest.

Direct infringement (dismissed with leave to amend). The amended complaint at one point used “Warner Bros.” to refer to a non-party, and its infringement charts accused a collective “WBD” platform of dozens of brands without tying specific acts or products to each named defendant. The court rejected BitHarmony’s “common sense” argument that one defendant infringes through HBO and another through Discovery products, because it did not distinguish the three Warner defendants or cover every accused product. A complaint against multiple defendants must identify each defendant’s specific infringing acts, but the court found the problem curable.

Key Takeaways

• In the District of Delaware, allegations of pre-suit knowledge based on industry participation, consortium membership or a predecessor’s licensing campaign, without a link to the defendant and the specific patent, are likely to be dismissed.
• A detailed complaint and expert declaration describing the prior art and how the claims improve technology can defeat an Alice step two motion at the pleading stage.
• A prior ruling in another court is not a substitute for a developed collateral estoppel argument, and an adverse ruling there may not help the movant if it found an inventive concept adequately alleged.
• Patent plaintiffs suing related corporate entities must say which defendant does what with which product.

Why It Matters

The decision illustrates how patent plaintiffs can use technical allegations to keep claims alive past the pleading stage on eligibility, while also showing the limits of knowledge and group-pleading theories that depend on inference. For companies that are accused as part of a corporate family, it supports demanding specificity about which entity is accused of what. For patent owners, it signals that discovery is the time to develop pre-suit knowledge theories, and that the court will consider a motion to amend if real evidence emerges.

The ruling is an early pleading-stage order. It does not decide whether the patents are valid or infringed.
