Protect Your Architectural Designs Before the Dispute Starts
BIM files, architectural drawings, planning submissions, and competition entries are high-value intellectual property, but ownership is difficult to prove without a cryptographic timestamp. Swiss Trust Layer applies ZertES + eIDAS certified e-Seals to your design files, creating court-admissible proof of authorship and existence date. Protect your work in under two minutes.
Three IP Risks Every Architecture Firm Faces
Architecture is a trust-based industry, but that trust breaks down in three recurring scenarios. Each one can cost you a commission, a competition win, or years of legal fees.
BIM File Theft During Contractor Handoff
You deliver a BIM model to a contractor for construction documentation. Six months later, the contractor's affiliated developer reuses core design elements in a new project. Without a timestamped seal on your original file, proving prior authorship requires expensive expert testimony and metadata forensics, and metadata can be altered. A cryptographic seal on the BIM export at the point of handoff creates an immutable, independently verifiable record that predates the disputed project.
AI-Generated Design Plagiarism
AI tools trained on large datasets can produce designs that closely mirror your published or submitted work. If your drawings appear in an AI training corpus, whether through a planning portal, a client website, or a design publication, derivative outputs may appear in competitors' proposals. Sealing your designs at the moment of creation, before public disclosure, establishes a timestamped prior art record that predates any AI output referencing your work. This is increasingly relevant as AI-assisted design becomes standard across the industry.
Competition Entry Disputes
Architectural competitions are high-stakes and frequently contentious. A sealed submission creates an immutable record: the exact file, at the exact time, with your firm's identity cryptographically bound to it. If another entrant submits work that resembles yours, or if an organiser misattributes designs between shortlisted teams, a ZertES + eIDAS certified seal gives you standing to dispute the decision with cryptographic evidence, not just correspondence and screenshots.
How It Works: Three Steps to Court-Admissible IP Protection
Swiss Trust Layer integrates with your existing workflow. You do not need to change how you create designs, only how you protect them at key handoff points.
Upload DWG, PDF, BIM Export, or IFC
Any file format is accepted: AutoCAD DWG, Revit export (PDF/DWF), IFC, Rhino files, SketchUp exports, or ZIP archives containing multiple drawing sets. The original file is never modified, only hashed.
Cryptographic Seal Applied
Swiss Trust Layer, via Swisscom Trust Services (Switzerland's leading ZertES-accredited QTSP), applies a PAdES/CMS-grade cryptographic e-Seal. The seal embeds a qualified timestamp, a cryptographic hash of your file, and a certificate chain traceable to an independently audited trust anchor. Any modification to the file after sealing is mathematically detectable.
Certificate with Timestamp and Hash
You receive a sealed certificate containing: the exact UTC timestamp of sealing (court-admissible under ZertES Art. 14 and eIDAS Art. 41), the SHA-256 hash of your original file, the Swisscom QTSP certificate chain, and LTV (Long-Term Validation) data ensuring the seal remains provable decades from now, even after the underlying certificate expires. The certificate is independently verifiable by any PDF reader or court-appointed expert without requiring access to Swiss Trust Layer's servers.
The Legal Foundation
Swiss Trust Layer seals are not proprietary assertions. They are backed by three overlapping legal frameworks that collectively cover Switzerland, the EU, and 181 Berne Convention member countries.
Art. 14 grants a qualified electronic seal the same evidential value as a handwritten signature under Swiss civil and commercial law. A ZertES-sealed file is court-admissible in Switzerland without additional expert authentication. Learn more about ZertES →
Art. 41 creates a legal presumption of accuracy for qualified electronic timestamps across all 27 EU member states. Because Swisscom Trust Services holds eIDAS QTSP accreditation, Swiss Trust Layer seals carry dual ZertES/eIDAS validity: one seal, valid in CH and EU. Learn more about eIDAS →
Architectural works are protected as artistic works under the Berne Convention without registration. A timestamped seal does not create copyright. Copyright arises automatically at creation, but it provides verifiable evidence of the creation date that courts in all Berne member countries can evaluate. This is particularly relevant in jurisdictions where establishing priority requires evidence of first fixation.
Six Scenarios Where a Sealed File Protects Your Firm
IP disputes in architecture arise at predictable points in the project lifecycle. Sealing at each handoff takes under two minutes and can prevent months of litigation.
Planning Submissions
Seal your planning application drawings before submission to the local authority. If the submission is delayed, modified, or attributed incorrectly in the official record, your sealed file establishes the original design intent with a precise timestamp.
Client Deliverables
At each project milestone (concept design, developed design, technical design), seal the deliverable package before handing it to the client. This creates a versioned, tamper-evident record that protects your firm if scope creep, design theft, or payment disputes arise later.
Competition Entries
Seal your competition submission package the moment it is finalised, before upload to the organiser's portal. The timestamp predates the submission deadline record, and the cryptographic hash binds the exact files you submitted, not a later version.
Subcontractor Handoffs
When sharing BIM models with structural engineers, MEP consultants, or specialist contractors, seal the model before each handoff. If a subcontractor later incorporates your design IP into a competing project, the sealed handoff record establishes what was shared, when, and in what state.
Joint Venture IP
Multi-firm projects require clear IP boundaries. Seal each firm's design contributions at the point of integration. If the joint venture dissolves or a dispute arises about which firm originated a particular design element, the sealed record resolves the question without relying on email timestamps or version control logs, which are easily disputed.
Concept Presentations
Early-stage concept presentations to prospective clients are a frequent source of IP loss. Firms present speculative designs in pitch situations, the client declines the commission, and the design appears in a subsequent project by a different architect. Sealing your presentation pack before each pitch creates a dated prior art record that deters copying and provides evidence if copying occurs.

Seal every BIM file at model milestones
Apply a qualified timestamp to each IFC or native model export when a design milestone is reached, before it leaves the studio.
Version-proof each drawing revision
Seal every issued revision so you can prove exactly which sheet existed at which date, independent of your CDE history.
Protect competition and tender entries
Seal concept boards and submission packages before they are shared, so authorship and date are fixed if the design reappears elsewhere.
