What It Is

PatentFiler is an online filing and follow-up management platform for U.S. USPTO provisional patent applications, backed by the intellectual property law firm Cislo & Thomas LLP. It is not positioned as a general-purpose project management or document SaaS tool. Instead, it packages provisional patent applications, attorney filing, deadline reminders, and document management into a standardized online workflow, helping inventors secure a filing date as quickly as possible and use “Patent Pending.”

Core Features and Collaboration Security

The platform’s core features include online submission of provisional patent applications, filing by a patent attorney, a 12-month non-provisional application deadline calendar, monthly reminders, Backend Management, portfolio views for multiple applications, tracking of status/serial numbers/filing dates, note saving and printing, prior-art link records, an IDS generator, patent assignment generation and recordation, trade secret registration, and SDS/SLS monthly guidance emails. Collaboration capabilities are disclosed only in limited detail: the site states that an authorized representative may submit on behalf of an inventor, but there is no visible support for enterprise teams, role-based permissions, approval workflows, or shared workspaces. On security, the website says it uses HTTPS TLS to encrypt information transmitted between the browser and server, but it does not disclose SOC 2, ISO, or more comprehensive data compliance details.

Pricing and Service Boundaries

Pricing is clear and based on USPTO entity type: $495 for micro-entities, $595 for small entities, and $795 for large entities. A one-hour attorney consultation costs an additional $250; post-filing patent search and opinion services cost $2,950. Compared with the article’s stated starting price of $3,500 for a law firm to prepare and file a provisional application, the platform has a lower initial cost. However, users should understand that provisional applications are not substantively examined by the USPTO and do not automatically become formal patents. A non-provisional application still needs to be prepared and filed within 12 months.

Pros, Cons, and Best-Fit Users

Its strengths are a vertical workflow, transparent pricing, included attorney filing, and a reminder mechanism, making it relatively friendly for independent inventors, engineers, product developers, and startup teams. Backend notes and deadline management can reduce the risk of missing critical dates. Its limitations are that the product scope is focused on U.S. provisional patents, while international or Chinese patent strategies still require professional representation; key legal consultation and search opinions cost extra; and information on APIs, third-party integrations, team permissions, payment methods, and SLAs is not disclosed.

Access from China and Alternatives

The crawled text does not provide information on access from mainland China, payment support, or localization, so access status is rated as unknown. For Chinese users whose goal is a U.S. provisional patent, PatentFiler can serve as a low-cost entry point. However, for matters involving Chinese patents, PCT applications, cross-border priority claims, and payment convenience, it is better to also consult a Chinese intellectual property agency. Comparable alternatives include LegalZoom, USPTO self-filing, and U.S. patent law firms.
