Virtual Patent Gateway (VPG) provides on-demand virtual paralegal support for attorneys, law firms, and companies in Patent Trial and Appeal Board (PTAB) proceedings. Our services can support visionary solo practitioners, boutique firms, general practice firms, and in-house legal departments by providing high-value work products while reducing overhead costs.


VPG's strength is its experience. Although founded in 2020, VPG has already supported over 100+ PTAB proceedings in various stages. And before launching VPG, founder Ashley Cheung worked for more than 20 years as a paralegal supporting patent disputes at a leading intellectual property law firm. She has established VPG as a client-driven business that supports work/life balance for VPG's team and clients.


Projects begin with a free consultation, led by Ashley, to understand the scope of support you need and to ensure that VPG is the best solution for you. VPG customizes all agreements and fees based on the level of support needed.


VPG's most popular services include:

  • Filings and service support of petitions, Patent Owner’s Preliminary Responses (POPRs), Patent Owner’s Responses (PORs), Replies, and Sur-Replies

  • Coverage of depositions and oral hearings from Petitioners and Patent Owners

  • Assistance with calculation of docket due dates prior and post-institution decisions*

  • Proofreading and cite-checking*


* VPG does not provide stand-alone docketing, cite-checking, or proofreading without a full engagement of its paralegal consulting services.
