Peritum Services

Peritum LLC provides independent and objective technical expertise to support every stage of patent litigation. Services include claim analysis, validity and infringement opinions, and clear expert testimony in court or deposition. With deep expertise in communications systems—including Wi-Fi and other wired and wireless technologies—the firm translates complex technical issues into language that is accessible to judges, juries, and attorneys alike.

From Verilog and RTL to firmware, databases, Wi-Fi protocol stacks, and high-level user interfaces, Peritum has the expertise to analyze code at every layer. This includes common programming languages such as C, Java, and Python, often used in Wi-Fi and communications software. We focus on identifying key functionality relevant to patent infringement and non-infringement analysis, showing how specific portions of code correspond to the features at issue. Complex implementations are translated into clear, well-documented findings that can be incorporated into expert reports, claim charts, and technical tutorials. By tracing functionality across hardware, software, and user-facing components, Peritum delivers analysis that is both technically rigorous and understandable to legal audiences.

Peritum designs and executes targeted, reproducible testing to evaluate product functionality in real-world conditions. Using tools such as Wireshark, spectrum analyzers, and protocol analyzers, alongside custom-built Wi-Fi and communications test setups, we capture detailed data on system performance and behavior. Field testing is conducted when appropriate to validate operation across diverse environments. This testing can be directly relevant to both infringement and non-infringement analysis, as well as to performance assessments that inform economic valuation and damages models. Each test is carefully structured and documented to ensure reliability, repeatability, and clear relevance to the issues in dispute. By combining industry-standard methodologies with tailored approaches, Peritum delivers testing results that provide a strong foundation for expert reports, depositions, and courtroom presentations.

Peritum brings decades of experience in the intersection of technical standards and patent policy. This includes deep expertise in interpreting and applying policies such as the IEEE-SA Patent Policy, particularly in relation to Wi-Fi (IEEE 802.11) standards, as well as familiarity with the practices of other leading standards organizations. Our work involves analyzing patent claims to determine whether they are standard-essential, providing clear insight into the relationship between technical specifications and intellectual property rights. Peritum also offers a nuanced understanding of relevant patent policies, their underlying purpose, and their practical implications in litigation and licensing. This combination of technical and policy expertise helps clarify essentiality determinations and FRAND obligations in a way that is both rigorous and accessible.

Peritum provides technical analysis that informs key economic determinations in patent disputes. This includes evaluating the technical value and benefits of patented inventions, as well as identifying non-infringing alternatives that may affect damages assessments. We also examine secondary considerations of non-obviousness—such as commercial success, industry adoption of Wi-Fi and related technologies, and technical advantages—where relevant to validity. In addition, Peritum conducts calculations and simulations to quantify performance improvements that may be attributed to a patent. By linking technical contributions to economic impact, Peritum delivers feature-level apportionment that supports reliable damages models and licensing negotiations.
