Pitching an unprotected screenplay to a studio or producer is the biggest IP risk a writer can take. A ZertES or WGA-equivalent certified timestamp creates irrefutable prior art. Here is exactly what to do before your first meeting.
In January 2025, a Geneva-based screenwriter named Sofia Meier pitched a limited series concept to a mid-sized European streaming platform during a development meeting. The pitch covered a six-episode arc, three specific characters, and a plot structure she had spent eight months developing. Fourteen months later, she recognized her story structure and two of her characters in a series announced by the same platform. Sofia had a PDF draft dated by cloud storage metadata. Her lawyer told her the timestamp would not hold up in a contested proceeding.
Every screenwriter is told to protect their script before pitching. Most do not know what protection actually means, which systems carry legal weight, and which systems fail at the moment they matter most: in a jurisdiction different from where the script was originally documented.
The Writers Guild of America (WGA) registration system is the most widely recognized screenplay protection service in the English-language film and television industry. Writers Guild of America West charges USD 25 for non-members; the registration creates a timestamped record maintained by the WGA.
WGA registration is credible within the US industry context for one specific reason: it is recognized by the US entertainment industry as standard practice. A script registered with the WGA has a record with a date, your name, and the content hash.
What WGA registration is not:
It is not legally qualified. The WGA is a labor organization, not an accredited certification authority. Its timestamp carries no legal presumption under any statute. In a US court, you would need to introduce the WGA record as evidence and argue for its probative weight. An opponent can challenge it as a private record maintained by an interested party.
It has no international legal recognition. WGA registration has no formal standing outside the US. A producer in Germany, Switzerland, the UAE, or South Korea has no legal obligation to treat WGA registration as proof of anything. If your script is pitched internationally, WGA registration provides limited protection.
It does not replace copyright. Copyright in a screenplay attaches automatically at creation in all 181 Berne Convention member states. WGA registration does not create copyright. It only creates a record that may be useful in establishing creation date in US disputes.
Screenplay ideas travel. A pitch to a production company in London, a co-production meeting in Zurich, a streaming platform meeting in Dubai. Your concept and story structure can cross borders in a single email.
Berne Convention membership (181 states) means your screenplay has automatic copyright everywhere. But automatic copyright without a documented creation date means that if a dispute arises in a foreign jurisdiction, you face proving your creation date under that jurisdiction's evidentiary rules.
A ZertES-qualified timestamp from Swiss Trust Layer resolves this problem directly. Swisscom Trust Services is simultaneously a ZertES-accredited certification authority (SR 943.03), recognized before Swiss courts, and an eIDAS-qualified trust service provider listed on the EU Trust List, recognized in all 27 EU member states under Regulation 910/2014, Article 41. A single Swiss Trust Layer certificate is legally credible in Switzerland and across the EU with full legal presumption.
Production companies and studio legal departments conducting due diligence on acquired or optioned material look for three things:
1. Clean chain of title. Every person who contributed to the script should have a documented agreement or release. If you co-wrote with someone, you need a written co-authorship agreement. If the script is based on existing material, you need documented rights to that underlying material.
2. Evidence of independent creation. If a script resembles a project already in development, the studio's legal team will ask for documentation of when your script existed in its current form. A ZertES or WGA timestamp is the documentary answer. A ZertES timestamp is stronger because it carries legal presumption; WGA registration is a private record.
3. No existing liens or competing claims. If you have previously pitched this material to other parties and received coverage notes, financial consideration, or signed any form of agreement, those facts need to be disclosed. Each prior pitch creates a potential chain of title issue.
For independent writers without agency representation, a ZertES-certified creation date plus a clear co-authorship record is the minimum credible IP documentation package.
If Sofia had sealed her six-episode treatment, the character documents, and the draft script with Swiss Trust Layer before that January pitch meeting, each certificate would have carried a Swisscom-issued qualified timestamp predating any platform development timeline. When her lawyer reviewed the announced series, the question would have shifted from "can we prove Sofia created this?" to "can the platform prove they developed this independently of her pitch?" That is the question a ZertES seal forces. Without it, Sofia carries the full burden of proof. With it, that burden moves. The EUR 250,000 to EUR 1.2 million in litigation costs that now loom over her case could have been avoided for CHF 5 per document.
Step 1: Finalize the draft you are pitching. Seal the version you will be presenting. If your pitch involves a treatment, a beat sheet, a Bible, or supporting materials, seal each document. Do not seal a work-in-progress you will continue to edit; seal the pitch-ready version.
Step 2: Seal with Swiss Trust Layer. Go to swisstrustlayer.com and upload your screenplay PDF. Your file is never stored. Only its SHA-256 cryptographic hash is transmitted. Swisscom Trust Services issues a qualified timestamp anchored to that hash. The entire process takes under two minutes.
Step 3: Receive and store your certificate. You receive a PAdES-compliant certificate containing the hash, the Swisscom-issued qualified timestamp, the issuer chain, and your identity. Store the certificate alongside your screenplay file.
Step 4: For each pitch or submission, seal the sent version. If you revise the script between pitches, seal each new version before sending. Create a version history. Each sealed version is a node in your documented development chain.
Step 5: After any pitch meeting, document what was discussed. A brief memo of what you disclosed, including logline, concept, characters, and specific story elements, sealed immediately after the meeting creates a record of the disclosure. If ideas surface in a later production that resemble your pitch, you have a documented record of what was communicated and when.
The SHA-256 hash is the mathematical fingerprint of your screenplay. Two documents that differ by a single character have completely different SHA-256 hashes. This means:
If a studio claims your script was inspired by their development, you can demonstrate that your sealed version existed before their development began. If they claim you saw their material and incorporated it, you can demonstrate that your story elements were sealed in your script before any contact with their material.
The hash does not lie. The Swisscom timestamp cannot be backdated. This is the cryptographic backbone of your legal claim.
For writers pitching internationally, the Swiss Trust Layer certificate provides different legal weight depending on jurisdiction:
EU jurisdictions: Full legal presumption under eIDAS Art. 41. Your ZertES certificate is treated as qualified electronic evidence by courts in Germany, France, Italy, Spain, the Netherlands, and all other EU member states.
UAE and GCC: The UAE Federal Electronic Transactions Law (Federal Decree-Law No. 46 of 2021) recognizes international trust service providers. A Swisscom-certified timestamp is credible independent evidence in UAE commercial proceedings.
US: No statutory presumption, but a Swisscom-certified timestamp from a globally recognized certification authority carries more evidentiary weight than WGA registration in any contested proceeding. US courts treat foreign authority certifications under rules of international evidence.
Switzerland: Full ZertES legal presumption. Strongest possible protection for pitches to Swiss co-producers and international partners operating under Swiss law.
Sofia is now weighing whether to pursue a claim that her lawyer estimates will cost between EUR 250,000 and EUR 1.2 million to litigate through to a verdict in an EU jurisdiction, based on EUIPO 2023 averages for IP infringement cases. She may prevail. She may not. A Swiss Trust Layer seal on her treatment and draft script before that January 2025 meeting would have cost CHF 5 per document. A sealed pitch is protected before your first meeting. Start at swisstrustlayer.com.
