Advanced Coding Technologies v. Apple: 5G NR Patent Suit Dismissed Same Day Filed
Advanced Coding Technologies LLC filed a three-patent infringement action against Apple in the Northern District of Texas, targeting the full iPhone 12–15 range, multiple iPad lines, and Apple Watch Series 9 for alleged 5G NR standard-essential coding technology. The case was voluntarily dismissed without prejudice on the same day it was filed — a pattern that typically signals a strategic procedural move rather than a merits resolution.
Three 5G NR Patents, 20+ Apple Products, Zero Days of Litigation
On 1 October 2025, Advanced Coding Technologies LLC (ACT) filed suit against Apple, Inc. in the Northern District of Texas, asserting infringement of three US patents — US9042448B2, US7804891B2, and US8230101B2 — all directed at wireless channel coding technology relevant to 5G New Radio (NR) standards. The accused product list was expansive, spanning the iPhone 12 through iPhone 15 families, multiple iPad generations including iPad Pro, iPad Air, and iPad mini, and Apple Watch Series 9.
ACT voluntarily dismissed the action without prejudice on the same date it was filed, invoking Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss as of right before the defendant files an answer or a motion for summary judgment. Because the dismissal was without prejudice, ACT retains the right to refile the same claims in any competent court, subject to applicable statutes of limitations and any preclusion doctrines that may apply.
The zero-day duration is notable and typically suggests the filing was part of a broader litigation or licensing strategy — potentially a venue-selection exercise, a negotiating catalyst, or a refiling in a different jurisdiction. The public record is silent on the specific motivation. No judicial rulings, claim constructions, or substantive determinations were made, leaving the strength of ACT’s three patents entirely untested in this proceeding.

Voluntarily dismissed: what Rule 41 without prejudice means for both parties
Rule 41(a)(1)(A)(i): Plaintiff’s unilateral right to dismiss
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. ACT exercised this right on the filing date itself. The dismissal requires no judicial approval and carries no merits determination — the court makes no findings on validity, infringement, or enforceability.
No merits adjudicationThe public record says ‘without prejudice’ — claims survive
A dismissal without prejudice means ACT’s infringement claims are not extinguished. The plaintiff retains the right to refile against Apple — or any other party — in any appropriate forum. This is legally distinct from a dismissal with prejudice, which would bar refiling. The verdict text in this case explicitly states ‘without prejudice,’ so ACT’s options remain open, though refiling risks and strategic considerations will govern next steps.
Claims may be refiledApple exits without conceding anything — but uncertainty persists
Apple filed no answer and made no substantive response before dismissal, meaning it obtained no favourable ruling on validity or non-infringement. The three asserted patents remain in force and could be reasserted in a new action. Apple’s legal costs in this proceeding were minimal, but the commercial risk posed by ACT’s patent portfolio — covering 5G NR coding technology in a broad product range — has not been resolved.
No declaratory judgment obtained5G NR coding patents remain a live threat across Apple’s product lines
With 20-plus accused products spanning iPhones, iPads, and Apple Watch, the potential damages exposure in any refiled action could be substantial. ACT is represented by Fabricant LLP, a firm with a track record in high-volume patent assertion. The same-day dismissal pattern often precedes a refiling in a more plaintiff-favourable venue or follows a breakdown in pre-suit licensing discussions, suggesting this dispute is likely not over.

Official order — verbatim text
The verdict text invokes Rule 41(a)(1)(A)(i) explicitly, confirming this is a plaintiff-initiated unilateral dismissal filed before any defendant response. The phrase ‘without prejudice’ is legally operative: it preserves ACT’s right to reassert the same infringement claims in a subsequent action. No judicial findings were made on claim construction, validity, or infringement. The court’s role was purely administrative — no merits analysis was applied, and neither party obtained any substantive legal advantage from this proceeding.
US9042448B2, US7804891B2 & US8230101B2 — 5G NR Wireless Channel Coding
The three asserted patents — US9042448B2 (App. No. 12/995039), US7804891B2 (App. No. 10/594985), and US8230101B2 (App. No. 12/527777) — are directed at wireless channel coding and data transmission technologies that underpin 5G New Radio (NR) standards. These patents cover techniques for encoding, decoding, and transmitting data efficiently across wireless networks, which are fundamental to the operation of any 5G NR-compliant device. The application genealogy across three separate application numbers suggests a broad portfolio with potentially overlapping claim scope.
Patents covering 5G NR coding methods are strategically significant because the standard is implemented across an enormous and growing base of consumer devices. Every major smartphone, tablet, and wearable with 5G connectivity is a potential infringement target if the asserted claims read on standard-compliant implementations. ACT’s decision to assert all three patents against Apple’s full 5G product range — rather than a single product line — is consistent with a maximum-leverage assertion strategy typical of well-funded NPE enforcement campaigns in the wireless technology sector.
Should your 5G NR product team run an FTO against US9042448B2?
Any company designing, manufacturing, or selling 5G NR-compliant devices — smartphones, tablets, wearables, IoT modules, or network equipment — should assess whether ACT’s three patents create freedom-to-operate risk. The accused product list in this case is a strong signal of claim breadth: if these patents potentially read on the iPhone 12 through 15 series and multiple iPad and Watch generations, they may also read on competing Android devices, chipsets, and embedded 5G modules across the supply chain.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map claim scope against product specifications, identify prosecution history estoppel, surface prior art that may support invalidity arguments, and monitor continuation filings from ACT’s portfolio. Given the same-day dismissal and likely refiling risk, proactive FTO analysis now — before a new complaint lands — is significantly less costly than reactive litigation defence.

What this case signals for the 5G NR patent enforcement landscape
A same-day voluntary dismissal without prejudice rarely marks the end of a dispute — it often marks a reset.
Same-day dismissals are a known litigation tactic, not a resolution
When a plaintiff dismisses without prejudice on the filing date, it typically signals a procedural strategy: venue shopping, a failed last-minute licensing discussion, or a coordinated multi-case filing reset. Companies monitoring ACT’s patent activity should not treat this dismissal as case closure — the three patents remain fully enforceable.
Fabricant LLP’s involvement raises the enforcement risk profile
Fabricant LLP is a specialist patent litigation firm with extensive experience asserting standard-essential and wireless technology patents. Their involvement alongside Brown Rudnick suggests ACT is well-resourced for continued enforcement. Any company operating 5G NR-compliant devices — not just Apple — should assess exposure to these three patents.
Advanced v Apple — key questions answered
ACT asserted three patents: US9042448B2, US7804891B2, and US8230101B2, all directed at wireless channel coding and data transmission technologies relevant to 5G NR standards. The accused products included the iPhone 12 through iPhone 15 families, multiple iPad generations, and Apple Watch Series 9.
ACT invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss without a court order before the defendant files an answer. The public record does not disclose the reason. Same-day dismissals without prejudice typically suggest a strategic procedural move — such as venue selection, a licensing negotiation reset, or a planned refile in a different jurisdiction.
No. A dismissal without prejudice explicitly preserves the plaintiff’s right to refile the same claims. ACT could reassert US9042448B2, US7804891B2, and US8230101B2 against Apple in any appropriate court, subject to applicable statutes of limitations. No merits determination was made in this proceeding.
The complaint targeted over 20 Apple products, including the iPhone 12, 12 Mini, 12 Pro, 12 Pro Max, iPhone 13 series, iPhone 14 series, iPhone 15 series, iPhone SE (2022), iPad (10th gen), iPad Air (5th gen), iPad Pro 11-inch (3rd gen and later), iPad Pro 12.9-inch (5th gen and later), iPad mini (6th gen), and Apple Watch Series 9.
ACT was represented by Fabricant LLP, Brown Rudnick LLP, Davis Firm PC, and Fabricant LLP (NY), with attorneys including Alfred Ross Fabricant, Vincent J. Rubino III, and Peter Lambrianakos. Apple was represented by Gillam & Smith, LLP, with Melissa Richards Smith as lead counsel of record.
