A newly granted U.S. patent (No. US 11981555) for multifunctional electric vacuum sealers has sparked potential legal action, putting numerous sellers at risk of infringement claims. Those currently marketing such products are urged to conduct immediate self-audits and take preventive measures.

Patent Details and Current Status

The patent was officially granted in May 2024. While no Temporary Restraining Orders (TROs) have been issued to freeze accounts yet, industry experts warn against complacency. Proactively identifying and removing potentially infringing products remains the most prudent approach to avoid legal complications.

About the Patent Holder

The enforcement action originates from Shanghai Xinqi Electronic Technology Co., Ltd., a Chinese company established in 2018 that specializes in the design, procurement, and distribution of household sealing products. The electric Mason jar sealer in question falls squarely within their product portfolio.

Product Overview

Electric Mason jar sealers have gained popularity as convenient kitchen tools designed to preserve food by vacuum-sealing glass containers. Their motorized operation offers significant efficiency advantages over manual vacuum pumps. Many models feature removable components for easy cleaning and sanitation, making them suitable for both home kitchens and outdoor activities.

Potential Risks for Sellers

Though widespread account freezes haven't yet materialized, patent enforcement actions often occur without warning. Should TROs be implemented, sellers could face immediate fund freezes that disrupt normal business operations. Legal professionals recommend that merchants currently offering electric Mason jar sealers should:

- Conduct thorough product reviews to assess infringement risks

- Remove questionable listings promptly

- Monitor developments closely

- Seek qualified legal counsel when necessary

The situation underscores the importance of rigorous patent compliance in the competitive home appliance market, particularly for products with innovative technological features.
