HI Mel,
After digging further i found that in July 1, 2014 Dropcam filed court action against e.DIGITAL on total of 6 Nunchi patents (514,522,523,524,618 and619)
Following day , July 2, 2014 e.DIGITAL had press release against Dropcam in regards to Nunchi patents infringement.
The Docket number 3:1401579 in USPTO matches Dropcam court action for July 1 , 2014..Things are getting very interesting indeed.
