The folks at Fusible have been doing some sleuthing on the possibility of Google putting together a social network based on photos.  They found that Google has trademarked the name Photovine with the following under the following areas:

Goods and Services IC 009. US 021 023 026 036 038. G & S: Computer software
IC 038. US 100 101 104. G & S: Communication services, namely, transmission of visual images and data by telecommunications networks, wireless communication networks, the Internet, information services networks and data networks

IC 042. US 100 101. G & S: Non-downloadable computer software

IC 045. US 100 101. G & S: On-line social networking services

Additionally, a company who uses MarkMonitor to anonymously register domain names has bought from a private holder.  Google is one of the companies that uses MarkMonitor.

Clearly that spells out a photo-sharing social network.

So, are Picasa/Picnik online services about to get more social under a new brand name?  All signs point to ‘yes’.
