PatentFiler.com is an online filing and follow-up management platform for U.S. USPTO provisional patent applications. It is not a general-purpose business SaaS product, but a vertical legal-tech tool: users submit provisional patent applications online, and the platform provides the USPTO application serial number and filing date by email within two business days. It also helps manage the critical 12-month window for converting the provisional application into a non-provisional application.
The platformβs core offerings include Patent Attorney Filing, a deadline calendar, monthly reminders, backend management, the SDS Success Development System, patent assignment generation and recordation, Trade Secret Registration, IDS Generator, and tools related to preliminary patent searches. The backend Dashboard lets users centrally view the status, serial numbers, filing dates, and submitted materials for multiple applications, while also saving and printing notes for each application. It can also record prior art information in preparation for later IDS disclosures. For uploads, the text states that PDF and JPG attachments are supported, with a total size limit of up to 20MB. If users already have a complete application, they can upload a PDF/JPEG and note βSee Attachedβ in the relevant fields.
The basic filing fees are clearly stated: USD 495 for a micro-entity, USD 595 for a small entity, and USD 795 for a large entity. Compared with the textβs reference to law firms charging from USD 3,500 to prepare and file a provisional application, the entry cost is relatively low. However, a one-hour attorney consultation costs an additional USD 250, and a post-filing patent search and patentability opinion costs USD 2,950. As such, it is best suited for quickly establishing a filing date first, then adding professional services as needed.
The advantages are a relatively straightforward workflow that brings filing, deadline reminders, follow-up educational emails, portfolio management, and notes into one system, supported by intellectual property attorneys from Cislo & Thomas LLP. The limitations are also clear: a provisional application does not automatically become an issued patent, and the applicant still bears primary responsibility for meeting the 12-month non-provisional filing deadline. Key legal judgments, search opinions, and non-provisional applications may still require deep attorney involvement. The text does not disclose any API, third-party integrations, team permissions, payment methods, or compliance certifications.
It is suitable for independent inventors, product developers, engineers, startups, and companies that want to quickly establish a U.S. provisional patent filing date. For Chinese users targeting the U.S. market, fundraising, or licensing scenarios, it can serve as an entry point for U.S. provisional applications. If the main goal is to protect the Chinese market, domestic patent agencies or relevant official Chinese systems should be prioritized. The crawled text does not provide information on network accessibility from China or payment options, so china_access is rated as unknown.
