Big companies like Google and Apple are thriving in today’s world not just because of they have good product lines but they do have range of “patent” lines too. So somehow patents are the real weapon these companies have and they are using it at the time of need. So a particular patent could be a maker or breaker for a company.
But look at this “William O Holmes Patent @ 1981”…… with my short sight I could see no immediate use of this patent. For those who are unable to understand this patent then these lines are for you: “The device and method of this invention provide for the insertion of a breathing tube through the water trap of a toilet to expose an open end thereof to fresh air from a vent pipe connected to a sewer line of the toilet, to enable the user to breathe fresh air through the tube”.
But important point is the type of toilet. This method is not always applicable in all kinds of toilet or you will breath Sh@T…….
