U.S. Patent Services for Domestic Clients

Strategic patent prosecution and post-grant counsel for companies, startups, universities, and innovators

AddyHart’s Divergent Patent Law practice helps U.S. clients identify, protect, develop, and defend valuable technologies. We combine technical depth, experienced patent prosecution, predictable pricing, and responsive service with substantial experience in patent appeals, inter partes review, ex parte reexamination, and Federal Circuit proceedings.

From the first invention disclosure through patent issuance, continuation practice, and challenges to issued claims, our objective is not merely to obtain patents. We work to build patent portfolios that protect commercially important technology, support investment and licensing objectives, and strengthen the client’s competitive position.

Patent Counsel Across the Patent Lifecycle

Patent strategy should begin with the business, not the filing form. Effective counsel must understand what the client is developing, which features create competitive value, how the technology may evolve, and how competitors could attempt to design around the resulting claims.

Our attorneys work directly with inventors, engineers, product leaders, and in-house counsel to develop patent strategies aligned with product roadmaps and commercial priorities. Our services span every stage of the patent lifecycle, from identifying new inventions and preparing patent applications to post-grant proceedings and appellate advocacy.

Patent Drafting & Prosecution

From invention disclosure through patent issuance, we help clients develop patent strategies that protect commercially meaningful innovations and support long-term business objectives. Our attorneys prepare and prosecute patent applications before the U.S. Patent and Trademark Office, guiding clients through Office Actions, examiner interviews, appeals, and portfolio development. Every prosecution decision is made with an eye toward claim scope, future continuation opportunities, and the long-term value of the resulting patent portfolio.

Semiconductor IP

Semiconductor innovation spans every stage of the technology stack, from device structures and fabrication processes to processor architecture, advanced packaging, and system-level design. We work with clients to develop patent strategies that protect commercially important innovations through coordinated claims covering devices, circuits, manufacturing processes, software, and system implementations. Our approach is tailored to where an invention fits within the semiconductor supply chain and how it may be practiced in the marketplace.

Consumer Goods IP

Consumer products often combine functional engineering, safety, usability, materials, and industrial design, requiring intellectual property strategies that protect both innovation and product design. We work with companies to identify protectable features early in the product-development process and develop coordinated utility and design patent portfolios. Our approach helps clients build meaningful protection for both how a product works and how it looks.

AI & Software IP

Software and artificial intelligence innovations require patent applications that clearly describe the underlying technological improvement and demonstrate how the invention advances conventional computer technology. We work with clients developing AI, software, cloud computing, cybersecurity, data analytics, and other emerging technologies to prepare strategically drafted patent applications and prosecution strategies. Our attorneys have substantial experience navigating patent eligibility under 35 U.S.C. § 101 while building patent portfolios designed for long-term commercial value.

Medical Device IP

Medical device innovation often combines engineering, software, clinical application, and regulatory considerations that influence both product development and patent strategy. We work with companies developing diagnostic systems, surgical instruments, implantable devices, digital health platforms, and other medical technologies to build coordinated patent portfolios. Our approach focuses on commercially meaningful claim scope, alternative embodiments, and long-term portfolio development that supports successful commercialization.

Post-Grant Proceedings

Post-grant proceedings require strategic advocacy that considers not only the immediate Patent Office proceeding but also its impact on litigation, licensing, and long-term portfolio value. We represent patent owners and parties evaluating challenges through inter partes review, ex parte reexamination, and related proceedings before the USPTO and PTAB. Our prosecution, appellate, and litigation experience allows us to develop strategies that protect valuable intellectual property throughout every stage of the dispute.

Unified Defense Program

The Unified Defense Program provides success-based representation for qualifying patent owners responding to ex parte reexamination requests filed by Unified Patents.
For accepted matters, the program offers a $20,000 success-based professional fee, payable only if the representation is successful and at least one challenged claim is confirmed as patentable, as defined in the written engagement agreement.

 

Program eligibility is subject to conflicts clearance, case evaluation, and a written engagement agreement. USPTO fees, experts, vendors, litigation, Federal Circuit proceedings, and other expenses are excluded unless expressly included. Prior results do not guarantee a similar outcome.

Why AddyHart

Experienced Attorneys

Our attorneys remain substantively involved in understanding the invention, developing the claims, interviewing examiners, and advising clients about consequential prosecution decisions.

Technical Depth

Our team handles technologies spanning semiconductors, software, artificial intelligence, medical devices, industrial automation, telecommunications, consumer products, mechanical systems, and advanced manufacturing.

Prosecution Informed by Patent Disputes

Arguments that appear expedient during examination may create unintended consequences during enforcement, licensing, reexamination, or post-grant review. Our experience beyond ordinary prosecution helps us evaluate those consequences before they become part of the public record.

Responsive Service

We provide clear recommendations, transparent budgets, and drafts sufficiently in advance for meaningful client review.

Portfolio Value, Not Patent Volume

The number of issued patents is not the only measure of success. We focus on whether the claims protect commercially important technology, create meaningful competitive leverage, and remain relevant as the client’s business evolves.
