Content Unavailable: Court Blocks 3 Streaming Patents as Abstract but Keeps Bit Rate Calibration
Video streaming technology is everywhere, but the patents behind it continue to face scrutiny under Section 101. In BitHarmony, LLC v. Amazon.com, Inc., Case No. 1:25-cv-02449, 2026 WL 1257368 (E.D. Va. May 7, 2026), Judge Anthony Trenga considered Amazon's motion to dismiss four of five asserted video processing and streaming patents.
Applying the Alice framework, Judge Trenga split the baby: Claims directed to encrypting and decrypting data, classifying data and applying rules, and recognizing video data for search purposes were held ineligible, but a claim directed to enforcing peak and average bit rate limits based on program type survived.
The decision offers useful guidance on where courts draw the line between abstract functional claims and those that recite a genuine technological improvement.
The Patents at Issue
BitHarmony asserted five patents against Amazon, four of which Amazon moved to dismiss: U.S. Patent Nos. 7,707,485 (the '485 Patent), 9,088,805 (the '805 Patent), 9,258,605 (the '605 Patent) and 9,124,954 (the '954 Patent). Each arose from a computer scientist who co-founded ViXS Systems Inc. – a semiconductor company that developed transcoding and video processing technologies and amassed more than 470 patents.
The '805 Patent: "Encrypted Memory Device and Methods for Use Therewith"
The '805 Patent, issued July 21, 2015, addresses the security risk that arises when uncompressed content sits in a buffer long enough for unauthorized parties to read and export it. The patent's solution: Use encryption and decryption as part of an "atomic operation" during memory I/O so that unencrypted content is never exposed in memory.
Claim 9 of the '805 Patent recites:
A method for processing video data, the method comprising:
generating an encryption key and a corresponding decryption key;
receiving the video data in a media format via an interface device;
unconditionally encrypting the video data into encrypted video data based on the encryption key when unencrypted video data is received via the interface device; and storing the encrypted video data in a memory device;
automatically decrypting the encrypted video data based on the corresponding decryption key when retrieving the video data from the memory device in conjunction with an encoding of the video data by a video encoder.
The '485 Patent: "System and Method for Dynamic Transrating Based on Content"
The '485 Patent, issued April 27, 2010, addresses the constraints of storage space and network bandwidth in digital video environments. The patent's solution: Dynamically modify encoding parameters (e.g., bit rate or resolution) in response to real-time analysis of content characteristics such as volume changes or motion vectors. The claimed innovation was using context-aware "rules templates" to drive encoding decisions based on "program information" rather than applying a single static compression standard.
Claim 1 of the '485 Patent recites:
A method comprising:
receiving, using a multimedia processing device, multimedia data representing multimedia content of a program;
identifying a select template of a plurality of templates based on the program using the multimedia processing device, wherein the select template comprises a plurality of rules, each rule comprising a characteristic and one or more actions to be performed by multimedia processing device in association with the characteristic, the one or more actions comprising at least one action selected from a group consisting of changing a bit rate of the multimedia data; changing a resolution of the multimedia data; and changing an audio Volume of the multimedia data;
analyzing the multimedia content using the multimedia processing device to determine characteristics of the multimedia content; and
modifying, using the multimedia processing device, the multimedia databased on an application of the plurality of rules of the select template to the characteristics of the multimedia content.
The '605 Patent: "System and Method for Transrating Based on Multimedia Program Type"
The '605 Patent, issued February 9, 2016, is a continuation of the '485 Patent. It claims to solve the inability of prior systems to adapt encoding constraints to specific content genres by establishing "peak bit rate" and "average bit rate" limits based on "multimedia program type" and scaling these limits. In other words: Reduce bit rate based on content type – what the patent calls "transrating" – so the video doesn't exceed the peak or average limits.
Claim 19 of the '605 Patent recites:
A system comprising:
a storage device;
an interface to receive multimedia data representative of a multimedia program;
a content analyzer operably coupled to the interface and configured to: determine a multimedia program type of the multimedia program; determine a peak bit rate limit and an average bit rate limit based on the multimedia program type, the average bit rate limit being different than the peak bit rate limit; and
a transcoder operably coupled to the interface and the content analyzer, the transcoder configured to transrate the multimedia data to generate transrated multimedia data having a peak bit rate not greater than the peak bit rate limit and having an average bit rate not greater than the average bit rate limit.
The '954 Patent: "Video Processing Device for Generating Time-Coded Metadata Based on a Search and Methods for Use Therewith"
The '954 Patent, issued September 1, 2015, covers recognizing data in a video and searching for related information – such as advertisements – based on what's recognized. The patent uses a "content analyzer" to generate content recognition from video signals, allowing a system to mine external information sources for content related to the video.
Claim 1 of the '954 Patent recites:
A video processing device comprising:
a content analyzer that receives a video signal and generates content recognition data based on the video signal, wherein the content recognition data is associated with at least one timestamp included in the video signal and wherein the content recognition data includes at least one keyword generated by recognizing video content in the video signal as corresponding to the at least one keyword; and
a metadata search device, coupled to the content analyzer and at least one external source, that searches for information in response to the content recognition data and generates time-coded metadata in accordance with the at least one timestamp the content recognition data and that includes the information, wherein the metadata search device searches the at least one external source, based on the at least one keyword, to identify the information
The Court's Analysis
Applying the two-step Alice framework, the court granted the motion as to Claim 9 of the '805 Patent, Claim 1 of the '485 Patent and Claim 1 of the '954 Patent – each drawn to abstract ideas without an inventive concept. But it denied the motion as to Claim 19 of the '605 Patent, finding that although the claim was abstract at Step One, it plausibly recited an inventive concept sufficient to survive the pleading stage.
Step One: Drawn to Abstract Ideas
Each of the four challenged claims failed Step One.
The '805 Patent claimed "nothing more than manipulating data using conventional encryption and decryption." The automatic or unconditional encryption process didn't move the needle. The court distinguished cases such as Ancora Technologies, Inc. v. HTC America, Inc., 908 F.3d 1343 (Fed. Cir. 2018) on the ground that those claims recited specific techniques departing from earlier approaches, whereas Claim 9 did not.
Claim 1 of the '485 Patent also failed Step One because it simply recited the result of classifying data and applying generic rules without specifying how those rules would apply. The court distinguished the rule-based process found eligible in McRO, Inc. v. Bandai Namco Games America, Inc., 837 F.3d 1299 (Fed. Cir. 2016), where the claim specifically recited rules "with specific characteristics" that enabled the claimed improvement. As Judge Trenga observed, courts have "routinely held that similar data classification and modification claims, without specifying how to achieve these results, are abstract."
Claim 19 of the '605 Patent likewise failed Step One because it did not explain how to determine a multimedia program type, set bit rate limits or transrate multimedia data. The court distinguished prior cases where the U.S. Court of Appeals for the Federal Circuit found the benefits of the invention derived from a claimed "programmable operational characteristic" that could be implemented using specific code attached to the patent. Claim 19, by contrast, "whose inventive benefit is allegedly targeted hardware calibration to achieve performance improvement unattainable by conventional, static systems," failed to specify any technical details for the tangible components.
Finally, Claim 1 of the '954 Patent failed Step One because, at its core, it was directed to recognizing data in a video and searching for related information – an abstract idea. The court relied on Content Extraction & Transmission LLC v. Wells Fargo Bank, N.A., 776 F.3d 1343 (Fed. Cir. 2014), and Intellectual Ventures I LLC v. Erie Indemnity Co., 850 F.3d 1315 (Fed. Cir. 2017), both of which held abstract claims directed to collecting, recognizing and storing data or using an index to search for and retrieve data. BitHarmony argued that generating "time-coded metadata" rendered the claim nonabstract, but the court rejected this – the claim did not specify how time-coded metadata "alters the landscape to overcome the 'static nature of traditional video presentation.'"
Step Two: No Inventive Concept (Mostly)
Three of the four claims lacked an inventive concept at Step Two. The '605 Patent was the exception.
On the '805 Patent, BitHarmony argued that the "specific arrangement" of encryption and decryption in conjunction with video encoding departed from conventional techniques and provided a non-generic solution to a security problem. The court disagreed. Claim 9 recited functional steps in their logical order with no non-conventional additions. As the court put it: Encryption and decryption keys must first be generated and video is received, encrypted, stored, decrypted and encoded – the standard sequence for any encryption process.
On the '485 Patent, the court rejected BitHarmony's argument that context-aware rules templates provided an inventive concept. Relying on GoTV Streaming, LLC v. Netflix, Inc., 166 F.4th 1053 (Fed. Cir. 2026), it found that the claimed rules did "nothing more than perform the 'ordinary function of carrying out the abstract idea' of data classification and modification" and that the claim lacked the specificity that "might go beyond result-focused functional language."
The '954 Patent similarly failed at Step Two. Relying on Intell. Ventures I LLC v. Erie Indem. Co., 850 F.3d 1315 (Fed. Cir. 2017) – which held that using a "well-known tag" to form a search index "did not transform the claim into something beyond a conventional computer practice" – the court rejected BitHarmony's argument that "dynamic, time-coded metadata synchronization" departed from the prior art.
Claim 19 of the '605 Patent, however, survived. Although the court found it abstract at Step One, BitHarmony had plausibly alleged that the simultaneous enforcement of peak and average bit rate limits based on program type constituted an inventive concept. The court concluded that discovery is needed to determine whether the limitations in Claim 19, "either individually or as an ordered combination, teach implementing the abstract idea using something more than well understood, routine, or conventional techniques."
Discussion
BitHarmony is instructive in several respects.
First, claims reciting functional results – encrypting data, classifying data, searching for information – without specifying how those results are achieved will be found abstract at Step One, regardless of the technological domain. The court's treatment of the '805 Patent is notable: Even though the patent addressed a real security vulnerability in video processing buffers, the claim's failure to detail how its "atomic operation" architecture worked doomed it. For patent practitioners drafting claims in the encryption, video processing and data analytics spaces: Reciting the what without the how remains a reliable path to ineligibility.
Second, the court's favorable treatment of the '605 Patent at Step Two offers a road map for surviving a Section 101 challenge even when a claim is found abstract at Step One. The distinguishing factor: specificity of the claimed technological contribution. The recitation of simultaneous enforcement of both peak and average bit rate limits based on program type was enough to raise a plausible allegation of inventiveness that could not be resolved without discovery. Compare that to the '485 Patent, whose "context-aware rules templates" were found to be nothing more than the abstract idea dressed up in functional language. The difference was granularity, not subject matter.
Third, the decision reflects the continued importance of Bascom's "non-conventional arrangement" framework at Step Two. The court's analysis of the '805 Patent demonstrates that reciting known components in their logical order is insufficient to invoke Bascom, even when the patent addresses a legitimate technical problem. For the arrangement to be "non-conventional," it must depart from the expected sequence. Mere automation is not enough. This is a recurring theme in post-Alice case law, and patent drafters ignore it at their peril.
Finally, the court's reliance on the recent Federal Circuit decision in GoTV Streaming signals that courts will increasingly demand that claims go beyond "result-focused functional language" to specify particular mechanisms or techniques. GoTV's admonition that "only features that are claimed, not unclaimed details that appear in the specification, can supply something beyond ineligible matter" appeared prominently in the court's reasoning – a reminder that specification-based arguments cannot rescue functionally claimed inventions at either step of the Alice analysis. The lesson: The inventive contribution must be claimed with specificity sufficient to distinguish it from the abstract idea it implements or it will not survive a motion to dismiss.
