message: Edcollins, I think you missed the point.
There may be published patents as submarines as well.
- patents that nodody was aware of for a long time, and then are rediscovered and enforced
- the market does not read patents in its field
- patent recherche fails as it is difficult to assess the targeted market, perhaps because of the wording
- patents that were pure "defensive" and later enforced (e.g. switch of ownership, patent strategy), e.g the Unisys patents on jpeg --Anon.
:The expression "submarine patent" originally refers to the practice of misusing the patent system to keep a patent application unpublished as long as possible. Interestingly you extend this definition to encompass all published patents that surprise the industry when they are enforced... I have never heard anyone extending the definition this way, but this is definitely an interesting derivation. Could you cite sources where such a meaning is conferred to the expression? A note in the article explaining this meaning derivation could be added then. Thanks. --Edcolins 09:25, Jan 7, 2005 (UTC)

thread_title:  How to submarine 

message: David, I removed your remark about possible EPC submarine patents. You have provided interesting food for thought, but unfortunately I believe it to be original research. Does any publication such as the epi Information discuss this issue? Cheers. --Edcolins 23:00, 24 November 2006 (UTC)
replies: text: Wasn't me this time!  I was quite surprised to see someone put it in...  Nothing verifiable as yet.  --Harris 07:29, 27 November 2006 (UTC)

thread_title:  European submarine patents II, still original research 

message: I removed "Extreme examples of U.S. submarine patents include , filed on July 25, 1933 and granted (and published) 67 years and seven days afterwards on August 1, 2000, and , filed on October 23, 1936 and granted on October 10, 2000."  The patents describe the rotor cipher machines that the U.S. used in WW II. These patents were delayed for national security reasons and I can't see where they have any commercial significance.  No one would be interested in this technology today. They are not examples of submarine patents.--agr (talk)
:Thanks. Indeed. I have added a note with a reference explaining this.  --Edcolins (talk) 20:22, 29 February 2008 (UTC)

message: In the bottom section of the article:
"Many of these patent claims, covering machine vision and bar codes, but 76 claims of his 14 patents were struck down in January 2004 by the federal district court in Las Vegas, Nevada:"
