Periscope up : Twitter UDRP against is quite overreaching

Once in a while, we see a major corporation, such as Twitter, exert its full corporate weight to squash improvisation.

In the UDRP case involving the domain, its Turkish programmer was forced to surrender a domain that in our opinion violated no trademarks.

Twitter acquired Periscope, a live video streaming service for between $75 million to $100 million dollars in 2015. Periscope’s popularity has grown so much that even Facebook recently copied it, launching Facebook Live.

Although the service, and subsequently Twitter, own a trademark for PERISCOPE, they do not own the .com; Periscope operates from

Mehmet Erdogan, a Turkish developer, created a useful meta-search engine for Periscope called Perisearch, allowing visitors to browse Periscope videos. Similar meta-search engines exist for Instagram and YouTube.

That didn’t sit well with Twitter, and in the UDRP that ensued some extreme allegations were made:

“Respondent’s <> domain name is confusingly similar to Complainant’s PERISCOPE mark. Respondent does not have any rights or legitimate interests in the <> domain name. Respondent registered and uses the <> domain name in bad faith.”

Twitter further alleges that the Respondent, who did not file a response in this far-reaching UDRP, attempts to pass off as Periscope, incorporating their logo as well.

Twitter’s claims are disputable, as a logo comparison indicates:


While Perisearch provided the ability to browse Periscope videos, it didn’t claim being a Periscope service. Apparently, its popularity annoyed Twitter.

The sole panelist’s decision is quite shocking:

“Respondent’s <> domain name is confusingly similar to the PERISCOPE mark because it contains a truncated version of the mark, “peri,” combined with the word “search” and the gTLD “.net.”  Complainant argues that “search” is a term that describes Complainant’s use of the mark for online search tools.  The Panel agrees and finds that the <> domain name is confusingly similar to the PERISCOPE mark.  “

The word “Peri-” is a Greek prefix, used to indicate an “all around” direction. The “Peri-” prefix can be part of many different words, and not exclusively for the word “Periscope,” which describes an instrument for viewing “all around.”
