Bosch Battery Patent Case Does Not Mean a Recall or Import Ban

As of September 26, 2026, the Bosch battery patent dispute has not produced an import ban, and it is not a battery-safety recall. The U.S. International Trade Commission has opened a patent-infringement investigation involving Bosch and several other companies, but it has not decided that a violation occurred. Its current case record lists the investigation as pending before an administrative law judge and shows no unfair-import orders.

For a Bosch owner or shopper, there is no case-based reason to stop using an undamaged pack or stockpile replacements. Availability would become a practical concern only if LG Energy Solution ultimately obtained an order covering particular imported products.

There are two related proceedings

Headlines can blur a federal lawsuit and a separate USITC investigation:

1. Federal patent lawsuit: LG Energy Solution Ltd. filed LG Energy Solution Ltd. v. EVE Energy Co., Ltd. et al., case 2:26-cv-00598, in the U.S. District Court for the Eastern District of Texas on July 21, 2026. The listed defendants include EVE Energy Co., Robert Bosch GmbH, Koki Holdings and Chervon entities. The public federal case docket shows that the court granted an unopposed motion to stay the case under 28 U.S.C. §1659(a) on September 9.

2. Section 337 import investigation: On August 20, the USITC instituted Investigation No. 337-TA-1518. Its respondents include Robert Bosch GmbH and Robert Bosch Tool Corporation, along with EVE Energy, Koki Holdings and Chervon entities. LG Energy Solution Ltd. and LG Energy Solution Arizona Inc. requested a limited exclusion order and cease-and-desist orders. Those are requested remedies, not orders now in force. The USITC announcement expressly says that opening the investigation is not a decision on the merits.

The official USITC case page listed the matter as pending before an administrative law judge and showed no unfair-import orders as of September 26, 2026.

What battery technology is involved

The investigation covers rechargeable cylindrical batteries, components and products containing them. Its official description names top-cap assemblies, electrode windings, separators, battery housings and assemblies. The five asserted patents are U.S. Patent Nos. 8,420,257; 11,749,866; 12,412,924; 12,412,965; and 12,646,735. The Federal Register notice identifies both the patent claims under investigation and the named respondents.

The patent documents address several subjects rather than one universal “tabless battery patent.” They include cap-and-gasket construction, safety-vent structure, a multilayer nanoporous separator, and wound-electrode or cylindrical-cell designs. Patent titles and descriptions explain the general subject matter; they do not establish that an EVE cell or Bosch product infringes a valid patent. That is what the proceedings must determine.

The official scope focuses on cylindrical cells and internal cell components. It does not say that Bosch’s slide rails, pack-to-tool fit or charging protocol infringe these patents.

Does this affect every Bosch battery?

The published institution notice does not support that conclusion. It defines a broad product category but does not give buyers a retail model-by-model list of accused Bosch packs. Naming Bosch corporate entities as respondents does not establish that every Bosch battery uses an accused cell or would fall within a future remedy.

This is also not a finding that Bosch batteries are unsafe. Although some asserted patents describe components with safety functions, the USITC notice alleges patent infringement; it does not direct Bosch owners to stop using their batteries.

Do not open a pack to try to identify its cells. Cell identity alone would not determine whether the asserted patent claims apply, and Bosch battery instructions warn against disassembly. Follow the operating and safety instructions for the exact pack and charger you own.

What could happen if LG wins

The remedy most relevant to buyers is a limited exclusion order. The USITC explains that this type of order directs U.S. Customs and Border Protection to exclude infringing articles originating from a specified respondent. A cease-and-desist order can prohibit a respondent from selling infringing imported articles already held in U.S. inventory. Both remedies require a finding of a Section 337 violation; neither has been entered here. See the Commission’s official explanation of Section 337 remedies.

The administrative law judge first develops the record and makes an initial determination, which the Commission may review. If the Commission issues a remedial order, it takes effect when issued and becomes final after a 60-day presidential review period unless disapproved for policy reasons, according to the USITC announcement.

The exact effect would depend on which products were found to infringe and how any final order was written. Different cell sourcing, a redesign, a license or a distribution change are possible commercial responses, but there is not enough public evidence to predict a Bosch battery shortage or price increase.

Buying or keeping Bosch tools

Treat this as a supply-chain issue to monitor, not a reason to leave the Bosch platform today.

• If you already own Bosch tools: Keep proof of purchase and warranty records. Continue following the instructions for your specific pack. The patent case itself does not change safe-use guidance.
• If you need one drill or replacement pack: Buy a pack and charger approved for that tool. The case does not make a bare cylindrical cell or an improvised adapter an appropriate substitute.
• If you are making a large platform commitment: Future availability is worth monitoring, but there is currently no order blocking Bosch products. Tool selection, local service, battery prices and the packs you already own are more concrete decision factors.
• If you are comparing battery labels: Ah and Wh are capacity-related ratings; they do not reveal patent status, cell supplier or guaranteed runtime. See Amp Hours vs Watt Hours for Cordless Tool Batteries before treating a larger label number as a complete performance comparison.

For updates, search for Investigation No. 337-TA-1518. As of September 26, 2026, claims that Bosch has lost this case or that its batteries have been banned are incorrect.
