Squeegees! Zipper pulls! Interactive vibrators!
The latter part of last century, before digital patents like the one for Generation node-B (GNB), (UE) and (MIMO) arrangements began to crowd out the entries for bottle cap removers, field cookers and vibrators (!), and when pagers and personal computers were still a hot commodity, Portland inventors applied for hundreds of patents.
