UPC evidence fees increased by 1,329% in 2026. Discover why litigation-grade translation is now a financial risk mitigation strategy for IP teams.<\/p>\n
On January 1, 2026, the Unified Patent Court put into effect a major overhaul of its fee structure. Most core proceedings such as infringement and revocation actions saw fixed fees rise by roughly one-third across the board.<\/p>\n
But one change stands out for everyone thinking about evidence: \u00a0applications to preserve evidence or for inspection orders jumped from \u20ac350 to \u20ac5,000. That is an increase of 1,329%.<\/p>\n
For IP teams and litigators, the message is clear. When a procedural step commands a four-figure investment, there is far less room for imprecision \u2014 including in the way evidence is translated.<\/p>\n
To understand this new scenario, we need to look at what changed in the UPC\u2019s fee structure, how evidence is now evaluated, and where language vulnerabilities are most likely to surface.<\/p>\n
The 2026 fee revision marks the end of the UPC\u2019s introductory phase and introduces a revised fee structure across proceedings. Nowhere is this clearer than in evidence-related applications.<\/p>\n
Until the end of 2025, evidence preservation functioned as a low-risk tactical tool. At \u20ac350 per application, it barely registered in litigation budgets and was often used as a probing move rather than a decisive procedural commitment.<\/p>\n
At \u20ac5,000, that dynamic fundamentally changes.<\/p>\n
In effect, the UPC has elevated evidence preservation to the same strategic tier as infringement and revocation actions. The fee increase also functions as a filter<\/strong>: weak, poorly prepared, or vulnerable to challenge applications are no longer economically tolerable.<\/p>\n 2025 Fixed Fee<\/p>\n<\/td>\n 2026 Fixed Fee<\/p>\n<\/td>\n Increase<\/p>\n<\/td>\n<\/tr>\n \u20ac11,000<\/p>\n<\/td>\n +32.7%<\/p>\n<\/td>\n<\/tr>\n \u20ac20,000<\/p>\n<\/td>\n +32.5%<\/p>\n<\/td>\n<\/tr>\n \u20ac11,000<\/p>\n<\/td>\n +32.7%<\/p>\n<\/td>\n<\/tr>\n \u20ac11,000<\/p>\n<\/td>\n +32.7%<\/p>\n<\/td>\n<\/tr>\n \u20ac350<\/p>\n<\/td>\n +1,328.6%<\/p>\n<\/td>\n<\/tr>\n \u20ac1,000<\/p>\n<\/td>\n +400%<\/p>\n<\/td>\n<\/tr>\n \u20ac2,500<\/p>\n<\/td>\n +484%<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n The conclusion is clear: evidence-related risk is now front-loaded. A single failed application represents a sunk cost that cannot be amortized at the outset of the case.<\/p>\n UPC litigation is inherently multilingual. Evidence often originates in German, French, Italian, or Spanish, yet must be filed in the language of proceedings under Rule 7.1 of the Rules of Procedure.<\/p>\n This creates a procedural choke point: translation is the gateway to admissibility.<\/p>\n In a court designed to reach oral hearings within roughly 12 months, linguistic weaknesses compound quickly.<\/p>\n If a defendant identifies material inaccuracies in a translated exhibit, the court may exclude the evidence entirely. After a \u20ac5,000 filing fee (plus inspection and expert costs), the claimant\u2019s evidence strategy can collapse in a single procedural motion.<\/p>\n Patent claims are linguistic precision instruments. A mistranslation that shifts how a claim feature \u201creads on\u201d to an accused product can break the infringement analysis.<\/p>\n UPC deadlines are tight and often non-extendable. If evidence is rejected due to translation defects, there may be no procedural window to correct and re-file before the written phase closes.<\/p>\n At this level of cost, translation errors are no longer easily correctable. In some cases, they may be impossible to remedy in time.<\/p>\n A translation can be scientifically accurate yet procedurally indefensible.<\/p>\n What the UPC increasingly demands is litigation-defensible language: terminology that aligns with:<\/p>\n This is where challenges under UPC Rule 7.2 come into play. Any perceived ambiguity gives the opposing party an opportunity to attack the accuracy of the translation itself<\/strong>\u2014forcing certification, court-ordered re-translation, or outright exclusion of the evidence.<\/p>\n Once \u20ac5,000 becomes the baseline cost of an evidence application, translation economics flip.<\/p>\n The relevant question is no longer \u201cHow much does the translation cost?\u201d It becomes \u201cWhat does a failed translation cost us?\u201d<\/strong><\/p>\n A challenged or excluded translation can trigger:<\/p>\n Against that backdrop, investing in defensible translation at the UPC is not an overhead expense. It is evidence insurance, a preventive measure designed to protect a significant procedural investment.<\/p>\n Another factor amplifying linguistic risk is the growing dominance of English. As of 2025, English accounts for approximately 54% of UPC cases<\/strong>, overtaking German as the dominant language of proceedings.<\/p>\n This trend is reinforced by the Court of Appeal\u2019s application of what commentators describe as a \u201cholistic fairness\u201d test when assessing requests to change the language of proceedings.<\/p>\n The court weighs:<\/p>\n Where interests are balanced, the defendant\u2019s position prevails, often favoring English.<\/p>\n For litigants, this means translations must remain robust even if proceedings shift languages mid-case. Preparing evidence for only the initial language is no longer sufficient.<\/p>\n The new fee regime demands a more integrated approach to evidence and language. Ask yourself these three strategic questions before translating evidence:<\/p>\n The UPC has increased the fee reduction for SMEs from 40% to 50% in 2026. While welcome, this does not eliminate risk.<\/p>\nUPC fee comparison 2025 vs. 2026.<\/strong><\/h3>\n
