Drum Unit Removal Request from Canon

Canon Inc. announced the filing of a Report Infringement Form with Amazon UK based on the alleged use of claim 1 of the UK portion of Canon’s European Patent EP 2 087 407 regarding the drum unit model “CE505A” offered by N&J Inkjet Ltd under the ASINs (Amazon Standard Identification Numbers) B00MWV9S3K, B00MWV8UYI, and B00MWV7ZZ8. Afterwards, Amazon took down the respective products.


These products are compatible with the drum unit of the OEM HP cartridge model CE505A and provide inter alia a non-OEM coupling member and a non-OEM drum. Filing a Report Infringement Form with Amazon is a service offered by Amazon and does not comprise any official finding of validity or infringement of a patent. The decision to take down a product is in the discretion of Amazon and is based on information provided by Canon. Amazon informed the vendor about the takedown and the vendor may object to it.
