Dear Rebecca Hanovice, Intellectual Property Counsel Callaway Golf.
At the time of Callaway's 2012 US patent ‘golf club head with improved aerodynamic characteristics’ there was an active US patent, showing drawings of a ‘golf club head with an aerofoil shaped hosel’ developed by Golf Refugees.
Can you please explain why this active US paper was not cited in Callaway's 2012 patent?
Happy to supply you with the relevant US Patent number(s) if required.
Here is what Callaway’s VP of Innovation & Design said to Golf Refugees via e-mail in 2006.
”I will be interested to hear what you may find in your wind tunnel testing. The club head is very large relative to the hosel, so it will be interesting to see if you can attribute drag or stabilizing effects to a single feature like that”
“Best of luck with the design work”
Regards,
Golf Refugees
