CHARLOTTE, Carolina del Norte, 12 de septiembre de 2019 /PRNewswire/ -- Celgard, LLC (Celgard), sociedad controlada de Polypore International, LP, ha resultado exitosa en su litigio por patentes en California contra Targray International of Canada (Targray) sobre violación de la patente por el separador de batería revestido con cerámica de Celgard (Patente EEUU Nº 6.432.586, ahora Patente EEUU Nº RE47.520) y la patente por el separador de polipropileno de Celgard (Patente EEUU Nº 6.692.867). Celgard y Targray han arribado a una conciliación de todos los litigios existentes entre las dos compañías en relación con las infracciones de Targray.

Membranas microporosas revestidas y no revestidas Celgard® utilizadas como separadores en distintas baterías de ion de litio.

Targray acordó cesar la venta, distribución o importación de todos los separadores de batería que se alegan en infracción, tales como los fabricados por Shenzhen Senior Technology Material Co., Ltd. ("Senior"), Senior International (HK) Co., Limited, W-Scope Corporation y Gelon LIB Co., Limited. Targray acordó que ya no habrá de usar, ofrecer para la venta, vender, distribuir ni importar ningún separador cubierto mundialmente por las patentes existentes de Celgard.

En la causa, Targray no disputó la violación, la validez o la exigibilidad de las patentes de Celgard.  Targray también acordó no objetar la validez de las patentes de Celgard '586 (ahora '520) y '867.

El resultado exitoso del caso contra Targray solidifica la integridad de la propiedad intelectual de Celgard respecto de los separadores revestidos y sin revestir para baterías de ion de litio.

Anteriormente, Celgard ya había arribado a conciliaciones en otras dos demandas contra MTI Corporation of California (MTI). La primera fue en un juicio por patentes en California bajo la misma Patente '586 que demandaba una compensación en razón de que MTI estaba vendiendo separadores de batería revestidos con cerámica fabricados en infracción por Foshan Jinhui Hi-Tech Optoelectronic Material Co., Ltd. en China. La segunda fue un juicio por marcas en Carolina del Norte, que exigía compensación de parte de MTI por vender separadores de baterías falsificados y no autorizados. MTI y varias relacionadas de MTI acordaron dejar de vender todos los separadores de batería revestidos y sin revestir.

Celgard continuará tomando las medidas apropiadas para prevenir la explotación ilegal de su tecnología y su propiedad intelectual a fin de proteger sus activos y a sus clientes.

Acerca de Celgard, LLC y  Polypore International, LP
