Version: 1.1 Effective Date: 2026-04-21 Last Updated: 2026-04-21
OpenArx respects the intellectual property rights of others and expects users of the Service to do the same. This Policy describes how copyright owners can notify the Operator of alleged infringement, how users may respond with counter-notices, and how repeat infringers are handled.
This Policy applies to:
Terms used in this Policy have the meanings given in the Terms of Service.
Copyright notices and counter-notices should be sent to the Operator at:
Designated Agent Vladyslav Kosilov, Operator of
OpenArx Email: [email protected] Subject line:
DMCA Notice — [short description]
The Operator acts as the designated agent for receiving notifications of claimed infringement in accordance with Section 512 of the United States Copyright Act (17 U.S.C. § 512), as well as equivalent notices under EU, UK, and other applicable law.
If You are a copyright owner or an agent acting on behalf of a
copyright owner, and You believe that material available through the
Service infringes Your copyright, please send a written notice to
[email protected] that includes all of the following:
Identification of the copyrighted work claimed to have been infringed. If the notice covers multiple works, a representative list is acceptable;
Identification of the allegedly infringing material and information reasonably sufficient to allow Us to locate it — e.g., the URL or stable identifier on the Service, the document ID, or the chunk identifier;
Your contact information — full legal name, mailing address, telephone number, and email address;
A statement that You have a good-faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law;
A statement, made under penalty of perjury, that the information in the notice is accurate and that You are the copyright owner or authorized to act on behalf of the copyright owner; and
Your physical or electronic signature (typed full legal name is acceptable for electronic submissions).
Notices that do not substantially comply with these requirements may be disregarded, though the Operator may, in its discretion, request missing information before processing a notice.
The Service's search method returns short text chunks
with bibliographic attribution, and its get_document family
of methods returns full text only for permissively licensed works (see
Terms of Service Sections 6.3 and 6.4). If Your notice concerns such
chunks, abstracts, or metadata rather than distribution of a full work,
please explain the specific elements You consider infringing so that the
Operator can evaluate the claim.
The Operator will take into account applicable exceptions — including fair use, quotation rights, the text-and-data-mining exception, and, in the European Union, the caching and hosting safe harbors — when evaluating such notices.
Under 17 U.S.C. § 512(f), any person who knowingly materially misrepresents that material is infringing, or that material was removed by mistake or misidentification, may be liable for damages, including costs and attorneys' fees.
The Operator is not required to verify the substance of a rights-holder's claim beyond the formal sufficiency of the notice. The statement under penalty of perjury required in element (5) of this Section, together with the signature required in element (6), are the principal assurances the Operator relies upon. Rightsholders bear the risk of misrepresentation under 17 U.S.C. § 512(f).
The Operator may, at its discretion, request clarification or additional information where a notice contains internal inconsistencies, appears to target material that is plainly non-infringing (for example, publicly available bibliographic metadata or author-provided abstracts), or raises red flags of bad-faith submission.
Upon receipt of a notice that is formally compliant with Section 3, the Operator will act expeditiously to:
The Operator's typical processing time for formally compliant notices is a small number of business days from receipt. The Operator does not guarantee any specific response time in individual cases but maintains operational capacity consistent with industry practice for similarly-sized services.
Malformed notices, notices requiring clarification, notices received during designated periods of low operational availability (for example, weekends and public holidays), and notices whose processing depends on third-party infrastructure response may be processed with additional delay. Such delay does not constitute non-compliance with this Policy.
The Operator reserves the right to decline to remove material where the notice is facially deficient, appears to be submitted in bad faith, or where the Operator determines after good-faith review that the use is plainly non-infringing (for example, lawful quotation, fair use, use under a valid Creative Commons license, or use under an applicable text-and-data-mining exception).
A rightsholder who has submitted a notice may request, at
[email protected], a copy of the log entries relating to
that notice. The Operator will provide the log entries subject to
redaction of information relating to other notices or other users.
If You believe that material You submitted was removed or disabled as
a result of mistake or misidentification, You may submit a
counter-notice to [email protected] containing:
Identification of the material that was removed or disabled and the location at which it appeared before removal;
A statement, under penalty of perjury, that You have a good-faith belief that the material was removed or disabled as a result of mistake or misidentification;
Your contact information — full legal name, mailing address, telephone number, and email address;
A statement that You consent to the jurisdiction of the appropriate court for the purpose of resolving the dispute, and that You will accept service of process from the person who submitted the original notice (or their agent);
Your physical or electronic signature.
Upon receipt of a compliant counter-notice, the Operator will forward it to the original complainant. Unless the complainant notifies the Operator within ten (10) to fourteen (14) business days that they have filed an action seeking a court order, the Operator may restore the removed material.
In accordance with 17 U.S.C. § 512(i), the Operator maintains a policy of terminating the accounts of users who are determined, in the Operator's good-faith judgment, to be repeat infringers.
Standard policy: a user who receives three (3) or more valid DMCA takedown notices within a rolling twelve (12) month period is considered a repeat infringer and is subject to account termination and forfeiture of any remaining credits or membership privileges.
The Operator may terminate accounts earlier in cases of egregious, willful, or large-scale infringement, or where required to maintain eligibility for safe-harbor protections.
This Section summarizes how the Service handles ingest and retrieval of scientific content from public sources, for the benefit of rightsholders considering a notice. The authoritative description is in the Terms of Service, Section 6.
The Service ingests scientific content from public sources under a unified processing regime — extraction, semantic chunking, embedding generation, and indexing — for the transformative purpose of semantic search and research assistance. Ingest is conducted in reliance on:
While ingest is unified, retrieval is tiered:
search method returns short chunks
(typically up to approximately 1,500 characters, in no case exceeding
5,000 characters) with bibliographic attribution and a link to the
canonical source, uniformly regardless of licensing status;get_document family of methods
returns full text only for permissively licensed works (CC-BY, CC-BY-SA,
CC0, public domain, and equivalent). For restrictively licensed or
default-license works, only bibliographic metadata, author-provided
abstract, and a canonical source link are returned.The search method returns only a small number of chunks
per document per query (typically up to two) selected by relevance.
There is no pagination through chunks of a work. As a consequence,
systematic reconstruction of a full work through successive queries is
not possible through the Service's intended interface.
For jurisdictions recognizing machine-readable opt-outs from
text-and-data mining (including EU Directive 2019/790 Article 4),
rightsholders who have declared such an opt-out — through formats such
as ai.txt, TDMRep, or comparable emerging standards — are
honored at the next ingest cycle. Individual notifications may also be
sent to [email protected] with evidence of the rights and
the opt-out declaration. The Operator will, where the opt-out is valid
and applicable, exclude the work from future processing and remove
derived representations where technically feasible.
If You believe a work has been indexed or served in a manner
inconsistent with its license — for example, the Service is returning a
chunk of a work whose rightsholder has declared a TDM opt-out, or is
serving full text of a work under a non-commercial license — please
contact [email protected] with relevant details. Such
requests are treated with priority.
The Operator relies on applicable safe-harbor frameworks for hosting providers and online services, including:
Nothing in this Policy limits any defense, exception, or limitation available under applicable law, including fair use (17 U.S.C. § 107), quotation rights, library and archive exceptions, or TDM exceptions.
For complaints concerning trademarks, publicity rights, or other
intellectual property rights not addressed by the DMCA framework, please
send a notice with equivalent content (identification of the right,
identification of the allegedly infringing material, Your contact
information, good-faith statement, and signature) to
[email protected] with the subject line
IP Notice — [short description].
Notices and counter-notices are forwarded to the other party to the extent necessary to resolve the dispute. Personal contact details (telephone number, physical address) may be redacted where appropriate. The Operator may also publish statistical information about notices received and actions taken.
The Operator may update this Policy from time to time. The "Last Updated" date at the top reflects the most recent version. Material changes will be announced on the Service.
