Summary of the 6 UPC Cases

Organizer: UPCLA (Unified Patent Court Lawyers Association)
10:00 AM - 11:00 AM

Between March and June 2024, UPC decisions clarified that third-party access under Rule 262.1(B) RoP is limited to party-submitted pleadings and evidence—excluding registry communications, court orders, and undefined future documents—with general-interest access allowed only post-decision, while specific-interest access (e.g., parallel EPO parties) may be granted during proceedings via a balancing test. On stays pending EPO opposition outcomes, the Court of Appeal set a near-absolute rule against stays under Article 33(10) UPCA/Rule 295 RoP, permitting them only where a truly rapid EPO decision is expected, and accepting procedural duplication to preserve the one-year timeline. Separately, in Photon Wave, the Paris Local Division refused to switch the language of proceedings from French to English and denied a late intervener extra time, illustrating the rules’ restrictive, fairness-limited application.

Decision form

Case 1: Bitzer v. Carrier
Court

Paris Central Division

Date

6 March 2024

Timestamp

05 : 29 – 07 : 35

Core Issue

Scope of Rule 262.1(B) RoP : whether access to written pleadings includes registry communications and court orders

Key Facts
  • Bitzer filed action against Carrier
  • Carrier filed late opt-out; statement of claim had defects remedied after opt-out
  • August Debouzy requested access to registry notifications and communications between claimant and registry
Legal Framework
  • Rule 262.1(B) of the RoP
  • UPCA provisions on public access
Main Ruling

Rule 262.1(B) applies only to written pleadings and evidence lodged by parties, not to communications between registry and parties, nor court orders

Significance

Clarifies narrow scope of document access – limited to party-submitted materials only

Case 2: Ocado v. Chris Stothers
Court

Court of Appeal (UPC)

Date

10 April 2024

Timestamp

07 : 40 to 20 : 30

Core Issue

Whether members of the public may access written pleadings and evidence during ongoing proceedings based on general interest

Key Facts
  • Nordic-Baltic Division granted access to Chris Stothers (journalist) to statement of claim and evidence from Ocado
  • Ocado appealed arguing that access should be restricted to post-decision phase only
Legal Framework
  • Rule 262.1(B) RoP
  • UPCA Article on public proceedings
  • principles of public access to justice
Main Ruling
  • General interest access permitted only after case concludes (decision or settlement)
  • Specific interest access permitted during proceedings
  • Requests must list documents and explain purpose/necessity
  • Balance of interests test required
  • Court may impose NDA-type restrictions
  • Access cannot be granted if request is abusive or violates public order
Significance

Establishes comprehensive framework for public access balancing transparency with protection of confidential information and proceedings integrity

Case 3: Nicoventures Trading v. NJOY & Juul Labs
Court

Paris Central Division

Date

24 June 2024

Timestamp

20 : 40 – 25 : 55

Core Issue

Whether UPC proceedings should be stayed pending EPO opposition decision

Key Facts

A claimant initiated revocation proceedings at the Paris Central Division (UPC) against a defendant, seeking to invalidate European Patent No. EP 3 430 921. An applicant party to parallel EPO opposition proceedings on the same patent submitted an access request under Rule 262.1(b) RoP on November 15, 2023.

Legal Framework
  • Article 33(10) UPCA
  • Rule 295 RoP
  • Concept of « rapid decision » from EPO
Main Ruling
  • General principle: no stay of proceedings at UPC
  • Stay only permissible if rapid EPO decision can be expected
  • Court has discretionary power on « rapid decision » assessment
  • UPC and EPO decisions are not irreconcilable (later decision prevails)
  • Duplication of proceedings is inevitable and accepted
  • No likelihood-of-success review required (unlike French practice)
Significance
  • Strongly restricts stay of proceedings
  • Prioritizes UPC efficiency over parallel EPO coordination
  • Establishes that procedural duplication is acceptable cost of parallel proceedings
Case 4: Carrier Corporation v. BITZER Electronics A/S
Court

Court of Appeal

Date

28 May 2024

Timestamp

27 : 54 – 38 : 00

Core Issue

Whether UPC proceedings should be stayed pending the outcome of parallel EPO opposition proceedings on the same patent, and what standard should apply to determine « rapid decision » from the EPO as contemplated by Article 33(10) UPCA and Rule 295 RoP.

Key Facts
  • Procedural Timeline:
    • June 28, 2024: Bitzer filed notice of opposition at the EPO
    • June 29, 2024: Bitzer filed revocation action before UPC against Carrier
    • Carrier filed request for acceleration at EPO and request for stay at UPC
    • EPO scheduled oral procedure for October 2024
    • UPC scheduled oral hearing for June 2024 (4-month gap)
    • EPO attempted to bring case forward
    • Carrier refused alternative April dates
  • Substantive Context:
    • Same patent involved in both proceedings
    • Similar arguments for invalidity in both actions
    • Carrier argued the EPO opposition had broader territorial and substantive scope than UPC revocation action
Legal Framework
  • Article 33(10) UPCA: Court must take proceedings when a rapid decision may be expected from pending EPO action
  • Rule 295 RoP: Parallel provision to Article 33(10)
Main Ruling
  • First Instance Court Decision
    • Rejected stay of proceedings on single ground: rapid EPO decision could not be expected
    • No assessment of likelihood of success of opposition (unlike French practice)
    • Reasoning: At that time, EPO had not yet scheduled oral procedure; no reliable prediction of timing possible
    • Foundational Principles in front of Court of Appeal:
      1. No Stay as General Rule: « There should generally be no stay of proceedings at the UPC »
      2. One-Year Timeline Objective: Proceedings must be conducted so oral hearing occurs within one year of statement of claim
      3. Non-Irreconcilability of Decisions:
        • UPC and EPO decisions are not irreconcilable, later decision prevails
        • Later courts can take into account earlier decision from another forum
        • This eliminates theoretical need for stay to prevent contradictions
      4. Narrow Exception « Rapid Decision » Standard:
        • Exception applies only if rapid EPO decision can be expected based on circumstances
        • Court has discretionary power to assess whether decision will be « rapid »
        • Acceleration requests from EPO are never sufficient – acceleration rarely enables EPO decision within UPC timeframe
      5. Application to Facts:
        • EPO oral procedure: October 2024 vs. UPC oral hearing: June 2024
        • Four-month gap is decisive; too substantial to justify stay
        • Court of First Instance correctly rejected stay
      6. Duplication as Inevitable:
        • Duplication of proceedings is acknowledged but deemed inevitable
        • Only alternative would be very long stay (2-3 years as in France) incompatible with UPC one-year guideline
        • Long stay conflicts with defendant’s interest in obtaining timely freedom-to-operate decision
      7. Party Conduct Considerations:
        • Opponent refused EPO acceleration, would have reduced opponent’s preparation time significantly
        • Court recognizes fairness considerations regarding party’s right to adequate preparation time
      8. Right to Be Heard:
        • Generally one round of pleadings sufficient for procedural issues like stay requests; two rounds not required
        • No violation of right to be heard in first instance
Significance
  • For UPC Practice:
    • Heavily restricts stay of proceedings – establishes near-absolute default rule against stays
    • Prioritizes UPC efficiency over coordination with parallel proceedings
    • Rejects French-law approach – no likelihood-of-success assessment required
    • Clarifies « rapid decision » standard as highly discretionary and fact-dependent, with strong presumption against satisfaction
  • For Litigants:
    • Very difficult to obtain stay
    • Only viable if EPO decision timing overlaps significantly with final UPC decision deadline
    • Must accept procedural duplication as normal cost of parallel proceedings
    • Cannot rely on EPO acceleration to justify UPC stay
  • For System Design:
    • UPC establishes independence from patent office proceedings
    • Demonstrates commitment to speedy first-instance resolution despite parallel EPO actions
    • Accepts risk of inconsistent outcomes as preferable to extended delays
