Patent Translation Companies: 5 Providers and an RFP Checklist
A source-backed company shortlist plus a reusable RFP, pilot scorecard, and contract checklist for patent-translation procurement.
Patent translation companies are easiest to compare when every candidate receives the same matter brief, pilot passage, pricing schedule, and contract questions. This page provides that procurement structure and an alphabetical five-company shortlist; it does not rank providers or repeat the broader choice between machine translation and professional service.
If that route is not yet settled, begin with Patsnap’s patent translation buyer’s guide. Then return here once the team has decided that a managed company should enter the evaluation.
Start with a purchasing brief
Before naming companies, document the matter that will be purchased: source and target languages, destination office or other legal use, document types, technical field, approximate volume, source-file condition, target format, certification or verification requirements, local-agent role, delivery milestones, and the person who approves legally material wording. For a PCT national-phase matter, WIPO directs applicants to office-specific National Chapters because translation requirements depend on the designated Office.1
This brief prevents false comparisons. One proposal may cover translation only; another may include independent revision, formatting, certification, foreign-filing coordination, or post-delivery corrections. Ask every candidate to price the same work breakdown and identify all exclusions. If the source application is still being prepared, resolve its structure and terminology first with a controlled patent drafting checklist.
Beyond translating an existing document, a team may also need to prepare a new patent application. Patsnap Eureka IP Drafting provides separate workflows for invention disclosure, patent drafting, and office action response, with support for CNIPA, USPTO, and EPO standards.4 It is not a patent translation company, and the linked drafting workflow does not replace review by qualified linguists or patent counsel.
Do not release the RFP until the matter owner and responsible patent professional agree on the source version, intended use, destination requirements, review responsibility, and deadline.
How this patent translation companies shortlist was built
A company was included only when its current official page explicitly described patent translation and contained enough detail for a narrow factual summary. The list mixes specialist and broader IP-service models so buyers can build a varied first-round candidate pool. It is alphabetical, non-exhaustive, and not a claim that these are the best providers.
The screen did not award points for unsupported superlatives, market position, unverified customer outcomes, or the mere presence of an ISO badge. ISO 17100 can help a provider demonstrate conformity of specified translation processes and resources, but the buyer must still examine the actual matter team and scope.3
A live, company-controlled page explicitly offers patent translation.
The page identifies document types, workflow elements, technical staffing, or adjacent filing support.
The entry can be written as a narrow paraphrase without repeating vendor superlatives.
Company size, quality, security, geographic strength, and suitability are not inferred from silence or branding.
Five patent translation companies to review
The following alphabetical shortlist is illustrative, not a ranking. Each company has a current official page that explicitly describes patent translation. Buyers should still verify the exact language pair, technical subject, destination-office workflow, reviewer qualifications, security terms, capacity, and commercial scope for the matter at hand.
Specialist technical translation
Language Scientific
Language Scientific describes filing and information translations and says it assigns patent translators and editors with technical degrees in fields such as engineering, science, medicine, and computer science. Its service page also distinguishes full translation, selective translation, and information-oriented work.7
Boutique IP translation
Key IP
Key IP presents itself as a boutique patent translation company covering patents, references, office actions, and supporting documents. Its page states that it works across PCT languages and technical sectors including biotechnology, engineering, high technology, and software.9
IP-focused agency
Patent Translations International
Patent Translations International says it focuses on intellectual-property translation and handles patent and trademark work, extracts, and filing support. Its published workflow describes a proofreader checking the translation against the source for accuracy, terminology, style, and formatting before a project-manager check.8
Patent translation and filing services
RWS
RWS describes a patent translation service that combines subject-matter translators with translation technology and professional review. Its page also presents an integrated route for translations and foreign filings through the inovia platform.5
Global IP services
TransPerfect IP
TransPerfect IP lists patent applications, Rule 71(3) claims, prior art, abstracts, drawings, office actions, litigation documents, and sworn translations within its patent translation offering. It also describes separate foreign-filing and portfolio-management services.6
RFP template for patent translation companies
Send every candidate the same controlled package and require a response against the same headings. Keep translation and foreign-agent costs separate from official fees; a broader patent cost framework can help organize those categories.
- Matter profile. Destination office or legal use, language pair, document types, technical field, source format, estimated volume, and milestones.
- Deliverable schedule. Translation, independent revision, formatting, certification or verification, query log, terminology file, clean final files, and delivery evidence.
- Staffing response. Qualification criteria for translator, reviewer, project manager, and any local agent; substitution rules; and escalation contacts.
- Technology declaration. Translation-memory ownership, approved machine-translation use, hosting and transfer locations, subcontractors, retention, and deletion.
- Commercial schedule. Unit basis, minimums, repeated text, project management, formatting, certification, rush work, revision rounds, taxes, currency conversion, and change requests.
- Exceptions. Procedure for changed source files, disputed terms, missed milestones, rejected files, quality complaints, post-delivery corrections, and urgent rework.
A quote is not comparable until every exclusion, dependency, source-file assumption, included review step, and client responsibility is written down.
Pilot scorecard before final selection
Use a short, representative, non-sensitive source passage and have the same qualified reviewer assess every candidate. The pilot is a procurement test, not permission to send confidential invention material through an unapproved channel.
Does the target text preserve each technical relationship, condition, alternative, and limitation without addition or omission?
Are dependencies, antecedent references, transitional phrases, and repeated claim terms handled consistently?
Are units, ranges, formulas, sequence identifiers, drawing numerals, and tables reconciled with the source?
Does the team follow supplied references, record uncertain choices, and distinguish a question from a silent assumption?
Are questions concise, material, traceable to the source, and directed to the right decision owner?
Are filenames, versions, tracked changes, clean files, issue logs, and delivery time handled as promised?
Record evidence and reviewer comments rather than one unexplained total score. A material change in meaning should remain visible even if the rest of the sample is fluent.
Contract and award checklist
Before award, convert the winning proposal into enforceable operating terms. The statement of work should identify the covered entities and language pairs, approved workflow, service levels, security schedule, subcontractor rules, deliverables, acceptance criteria, pricing schedule, and order-of-precedence rules.
Name who owns source approval, translation, independent revision, legal review, deadline monitoring, local filing, and final acceptance.
Define how source revisions are identified, priced, translated, reconciled, and approved without mixing versions.
Set notification, root-cause, rework, escalation, and record-update obligations for errors found before or after delivery.
Require return or export of final files, terminology assets, decision logs, open issues, and deletion or retention confirmation.
A translation company provides language services; patent counsel or an authorized local agent makes legal and filing decisions. The contract should not leave claim amendments, certification, deadline calculation, or filing approval implied.

Frequently asked questions
How many patent translation companies should enter an RFP?
There is no universal number. Use enough candidates to compare materially different service models while keeping the pilot and legal review manageable. Eliminate any company that cannot confirm the required language pair, technical staffing, workflow, security terms, or deadline before the pilot.
How can quotes be normalized?
Issue one pricing schedule that separates translation, revision, project management, formatting, certification, local-agent work, rush handling, minimums, repeated text, taxes, and source changes. Record exclusions and volume assumptions beside each price.
Should the same passage be used for every pilot?
Yes, if confidentiality and procurement rules allow it. The same source and instructions make reviewer comments more comparable. Choose material that represents the actual technical and claim-language difficulty rather than an easy marketing paragraph.
What should happen after a successful pilot?
Confirm the proposed production team, reconcile contract terms, define an initial controlled matter, agree reporting and escalation, and schedule an early service review. Do not assume the pilot team, tools, or workflow will automatically carry into production.
Can Eureka replace a patent translation company?
No. This page links Eureka IP Drafting only for the separate task of preparing and reviewing new application material. The linked workflow is software, not a managed translation company; use qualified language professionals and patent counsel for filing or legal-reliance translations.
