Memjet and HP settle patent dispute

Memjet and HP have reached a settlement that sees the two companies drop the various actions between them and agree a cross-licensing arrangement.

The dispute started last summer when Memjet claimed that HP had infringed eight of its patents around its pagewide Waterfall printhead in HP’s PageWide printers, including its T-series commercial presses as well as the wide format CAD printers and Pro X office printers. Memjet has some 3500 worldwide patents for its high speed thermal inkjet technology.

Initially Memjet won an injunction in Germany to prevent sales of the PageWide wide format printers, but HP later overturned this and instigated a review of Memjet’s patent filings. One of the stumbling blocks appears to have been that both companies have used their respective print technologies to develop 3D print solutions, something that neither had envisaged in their original patent applications.

Naturally neither company has commented on the terms of the deal.

You can license the articles from Printing and Manufacturing Journal to reproduce in other publications. I generally charge around £150 per article but I’m open to discussing this for each title, particularly for publishers that want to use multiple stories. I can provide high res versions of images for print publications.

I’m used to working with overseas publishers and am registered for VAT with the UK’s HMRC tax authority but obviously won’t charge VAT to companies outside the UK. You can find further details and a licensing form from this page, or just contact me directly here.
