Signal Processing Expert Witnesses

Signal processing disputes in commercial litigation typically arise in patent, telecommunications, and consumer electronics matters, when a company alleges that a competitor's audio, image, video, or wireless communication technology infringes a patented signal processing method. These disputes surface in patent infringement litigation over algorithms used in audio compression, image processing, and wireless communication systems, in licensing disputes over the scope of permitted use for signal processing technology in consumer or industrial products, and in product liability and performance disputes over whether a device's signal processing capabilities met contractual or advertised specifications. Because signal processing techniques involve specific mathematical algorithms applied to audio, image, or wireless signals, determining whether an accused product practices a claimed method requires expertise in the specific signal domain at issue. The central issue is typically whether the signal processing technology at issue functions or was implemented in the manner the patent, contract, or specification described.

A signal processing expert helps attorneys resolve that question by analyzing the algorithms, architecture, and performance of the technology at issue against the patent claims or specifications in dispute. That might mean comparing an accused audio or video compression algorithm against a patent's claimed method, evaluating whether a wireless communication system's signal processing techniques meet the performance specifications a contract requires, or assessing whether a licensed signal processing technology was used within the scope its license permits. These technical findings support positions on patent infringement, breach of contract, and licensing compliance, and often anticipate the arguments an opposing technical expert is likely to raise.

Because signal processing spans audio, image, video, and wireless communication domains that each require distinct technical expertise, selecting the right expert means matching the assignment to someone with hands-on experience in the specific signal domain at issue rather than signal processing in general terms. Round Table Group's signal processing network includes electrical engineers with expertise in adaptive filtering, telecommunications, and image and video signal processing, several of whom have testified in patent cases involving video compression and communications technology. With more than 75,000 expert searches completed for litigators, we help attorneys match a case's specific signal processing issue to an expert whose credentials will withstand scrutiny.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Signal Processing expert witnesses for cases like:

01

Wireless Audio Codec Patent Dispute.

Two consumer electronics companies litigated over a patented audio compression algorithm after one company's new line of wireless earbuds incorporated a codec that closely mirrored the other's patented encoding technique. We identified experts with experience in digital signal processing, audio compression algorithms, and technology patent claim analysis. The expert's technical comparison of the encoding architectures supported a finding of infringement, resulting in a licensing settlement exceeding $20 million.
02

Streaming Video Codec Royalty Dispute.

A video codec licensor sued a major streaming platform after an audit revealed the platform had significantly underreported the number of devices using its licensed video compression technology, resulting in years of underpaid royalties. We identified experts with experience in video compression technology, codec licensing structures, and digital signal processing. The expert's technical audit of the platform's deployment confirmed the extent of the underreporting, driving a substantial settlement.
03

Defense Radar Signal Processing Underperformance.

A defense contractor sued its radar subsystem subcontractor after the delivered signal processing system failed to achieve the contracted target detection range during acceptance testing. We identified experts with experience in radar signal processing, RF systems engineering, and defense systems testing standards. The expert's independent test analysis confirmed the system's detection performance fell well short of the contracted specification, anchoring a substantial settlement.
04

Seismic Subsurface Imaging Processing Dispute.

An oil and gas exploration company sued its seismic data processing contractor after a flawed subsurface imaging deliverable led the company to drill a well in a location later shown to lack the represented reservoir characteristics. We identified experts with experience in seismic signal processing, geophysical data interpretation, and subsurface imaging methodology. The expert's reprocessing of the raw seismic data revealed significant processing artifacts that had distorted the original imaging, supporting a substantial recovery.
05

Medical Imaging Signal Processing Defect.

A medical device manufacturer sued its imaging software supplier after a signal processing algorithm embedded in its diagnostic imaging platform was found to introduce artifacts that compromised diagnostic image quality across a significant share of deployed systems. We identified experts with experience in medical imaging signal processing, diagnostic image quality assessment, and biomedical software validation. The expert's testing confirmed the algorithm's artifact rate exceeded accepted diagnostic imaging standards, driving a favorable settlement.
06

Speech Recognition Engine Accuracy Dispute.

An enterprise software company sued its speech recognition technology licensor after the licensed engine's word accuracy rate in real-world deployment fell significantly short of the rate warranted in the licensing agreement. We identified experts with experience in speech signal processing, automatic speech recognition systems, and algorithm performance benchmarking. The expert's independent accuracy testing confirmed the shortfall, supporting a substantial recovery.
07

Hearing Aid DSP Recall Claim.

A hearing aid manufacturer sued its digital signal processing chip supplier after a noise cancellation algorithm embedded in the chip caused audible distortion across a significant share of a product line, forcing a costly recall. We identified experts with experience in hearing aid signal processing, audio DSP algorithm design, and acoustic performance testing. The expert's testing traced the distortion to a flawed adaptive filtering implementation, shifting liability for the recall costs to the chip supplier.
08

GNSS Receiver Positioning Accuracy Dispute.

An autonomous vehicle company sued its GNSS receiver supplier after the delivered positioning module's real-world accuracy fell significantly short of the specification represented in the supply agreement, delaying the company's testing program. We identified experts with experience in GNSS signal processing, positioning algorithm design, and satellite navigation systems testing. The expert's field testing confirmed the module's positioning error exceeded the contracted tolerance, anchoring a favorable settlement.
09

Marine Sonar Detection Performance Dispute.

A marine equipment company sued its sonar signal processing subcontractor after a delivered sonar system failed to achieve the contracted target detection performance during sea trials. We identified experts with experience in sonar signal processing, underwater acoustics, and marine systems testing. The expert's analysis of the trial data confirmed the system's detection algorithm underperformed its specified thresholds, driving a substantial recovery.
10

Trading Market Data Latency Dispute.

A proprietary trading firm sued its market data signal processing vendor after intermittent latency spikes in the vendor's data feed processing system caused the firm to miss a significant number of time-sensitive trading opportunities. We identified experts with experience in low-latency signal processing systems, financial market data infrastructure, and network timing analysis. The expert's analysis of system logs confirmed the latency spikes exceeded the contracted performance thresholds, supporting a substantial settlement.
