A Follow-Up Posting… If You Can’t Identify This Driver Then You Must Not Be A Golfer…

A prior post illustrated a design patent on the sole features of a particularly recognizable square driver. This week a design patent issued on some identifiable crown features of that same driver. Can you identify the driver?… I suspect there will be many more design patents on this product line. The club manufacturer has also filed a utility patent application related to the product. The application has published as US Pub. No. 20050239576 and is currently under examination at the USPTO…

Another Famous Instructor and Inventor, David Leadbetter

As a follow-up to my post on Dave Pelz, I felt a look at David Leadbetter was in order. If you are not familiar with David Leadbetter, he holds the #2 position on Golf Digest’s list of the greatest American teachers. Anyone that has built such a successful golf instruction career must have invented some interesting golf products in his many years in the industry. Right? Also, given that the likes of Ernie Els, Michelle Wie, and Charles Howell III listen to him, I suspect that anything David has invented will actually improve a golfer’s …

What is Behind the Hollow Metal Core Golf Ball Hype? MOI of Course

I have been keeping my eye on the NanoDynamics hollow metal core golf balls for some time now. The NDMX line of golf balls seem to be getting a lot of press because they are so unique (as they should be for $60 / dozen). NanoDynamics indicates that the hollow metal core technology is covered by three of their patents. The primary goal of the invention appears to be improving the moment of inertia (MOI) of the ball by minimizing the density in the center of the ball, while maximizing the density away from the center and near the cover or outer edge of the ball…

New Callaway Commercial Featuring Roger Cleveland (formerly of Cleveland Golf)

Have you seen the Callaway Golf commercial featuring Roger Cleveland? Roger explains how he formerly owned a golf company (read between the lines… Cleveland Golf) but now works for Callaway (… and something about innovative designs). I thought it would be fun to see if he is listed as an inventor on more patents assigned to Callaway Golf or Cleveland Golf. Given the disparity in size between the two companies it should be no surprise that he is listed as an inventor on eight times as many Callaway patents. In fact, he is listed as an inventor on more Callaway …

Thinking of Landing that Next Great Job by Taking Your Employers Trade Secrets? Consider that an Ex-Coke Employee just Received 8 Years in the Clink

As with most industries, it is not uncommon to see a golf product engineer working for company X one year followed by company Y the next year. In fact, many employees view job jumping as the method to get the pay raise that they deserve. Undoubtedly, these engineers know a lot of confidential information about company X, particularly information regarding products under development and other research and development programs. While company Y may be extremely excited about the opportunity to have an experienced industry insider join their team, they must keep in mind that with experience comes baggage, and precautions … Just consider the trade secret lawsuit that Nike is involved in… Do you think Nike would have made the hire if they had known they would find themselves right in the middle of a trade secret lawsuit?…

Can Membership at Augusta Cost Your Company Millions?

It probably goes without saying that anyone who has followed the game of golf over the last several years has heard the name Martha Burk. In 2002, Burk, the former chairwoman of the National Council of Women’s Organization (NCWO), led a campaign to open the gates of the Augusta National Golf Club to women members. Although the efforts of Burk and the NCWO did not succeed in establishing a single woman member at Augusta, their work has since developed into the “Women on Wall Street” project. This initiative targeted many of the nation’s largest financial institutions whose top executives were members at Augusta, and …

A Few More Interesting Golf Club Trademark Applications Filed So Far This Year – Perhaps We Will Soon See a PING Phapsody, Taylor Made r11, or Taylor Made Black Max on the Market

Yesterday a few 2007 trademark applications of Callaway Golf were reviewed. Today let’s look at what a few of Callaway’s competitors have in mind for new product offerings based upon their trademark application filings so far in 2007. It looks like everyone is looking for a catchy name for their hybrids. As I mentioned yesterday, Callaway has filed a trademark application for FT i-brid. Not to be outdone, Nike has filed a trademark application for a Midbrid trademark. Karsten has filed a trademark application seeking protection of the …

A Look at Callaway’s Trademark Filings this Year – A Potential Glimpse into New Product Offerings

One of my first posts on the Golf-Patents blog discussed using trademark filings as a source of competitive intelligence. Well, an update (or some updates) are in order. Let’s look at a few of Callaway’s trademark filings so far in 2007. The results show that Callaway has some pretty creative branding people and they plan to ride the wave of the “square” club head popularity as long as they can. For instance, why would anyone play regular old “fairway woods” when they could play Callaway’s SQUAREWAY WOODS. Or perhaps the product line will be …

Breakthrough in Golf Cart Design… Perhaps Not

Earlier this week I authored a post that takes a look at the patents of Dave Pelz, Phil Mickelson’s short-game coach. It got me thinking… is Butch Harmon, Phil’s other coach, listed as an inventor on any patents? Well, the answer is no… but in the process of researching the issue I happened across an interesting invention of a Mr. Al Harmon (I have no idea if they are related). Al’s invention (disclosed in USPN 4,792,149 is a pedal powered golf cart. Interesting concept. Would you pay to rent a cart that you had to pedal? Check out the following figure from the patent…

Some Driver Manufacturers Tune Club Heads for that Perfect Sound… Others Seek to Attenuate (Deaden) the Sound of Impact

Today’s drivers sound a lot different than clubs of ten years ago. The changes are largely associated with the changes in the materials used in the construction of drivers. Now days virtually every driver incorporates titanium alloys, and many incorporate composite materials. With regard to the sound of impact, manufacturers can choose to either (a) ignore how the club sounds at impact (not smart), (b) tune the club head to achieve a desirable sound at impact (see this post), or (c) seek to reduce, or attenuate, the sound of impact. Last week Acushnet was granted a patent directed at the later; namely reducing, or attenuating, the sound of impact….

Patents by Dave Pelz – Phil Mickelson’s Short-Game Coach

After watching the Players Championship this weekend there is little doubt that Michelson has one of the best short-games in the past twenty years. Perhaps there is something to Dave Pelz’s instruction. Ever wonder if he has patented any golf instruction aides? It turns out that Dave Pelz is a listed inventor on 12 golf patents. He has patented everything from sets of wedges with specific groove shapes and spacing to putters and putter practice aides. The patents are really some interesting reading (and I bet most of his inventions do actually improve your game). Check out the following…

Likely to See This Head Cover at The Players Championship?

Sometimes patent attorney’s can become jaded (hard to believe, I know). For instance, the first thing I said to myself when I saw the patent application that published yesterday as US Pub. No. 20070102082 titled “Golf Club Cover” was… “how many of these novelty head covers must the inventor sell just to cover the cost of the patent application?” Nonetheless, the invention is somewhat amusing (in a “cute, but I would never buy it” kind of way). See what you think. The application describes the invention as: “The present invention is directed at a humorous club head cover. The club head cover is designed to resemble the rear end of an animal…

IP Grab of the Week: Another Interesting Golf Club Shaft Patent Application

Things appear to be heating up in the golf shaft patenting arena. Regular readers of the Golf-Patents blog know that I was surprised by the low number of golf shaft related patents that issued in 2006… This week another interesting shaft patent application published as US Pub. No. 20070105644 titled “Golf Club Shaft.” The application is assigned to SRI Sports and is directed to an improved golf club shaft made of fiber reinforced resin… Let’s face it, very few golfers ever consider the amount of engineering R&D that does into the design of a golf club shaft. If you have ever wondered why shafts can be pretty expensive just read this application. The design, orientation, and placement of the multiple plies are engineered to a level that few people can appreciate. Just consider the figure below illustrating the various layers that make up this shaft.

The True Cost of Patent Litigation

Patent litigation is expensive! There is no way around it. This is true whether a case settles after 2 months, 2 years, or goes all the way through trial. There are ways to more efficiently litigate a patent infringement case, but that is for another post. Generally when companies discuss the cost of patent litigation they only focus on the legal costs (i.e. what the law firm representing them has charged). Those of you that have been involved in a protracted infringement case know that the cost associated with the burden placed on a company’s key people may … “We find that firms lose about half a percentage point of their stock market value upon being sued for patent infringement. This corresponds to a mean cost of $28.7 million in 1992 dollars (median of $2.9 million), much larger than the mean legal fees of about half a million.”…

Fascinating IP of the Week – Ridiculous Club Design or the Next Great Breakthrough?

As you may recall the “Fascinated IP of the Week” category is the resting ground for golf inventions that I can’t identify as the next great golf technology or a ridiculous idea (although generally I have a pretty good hunch). The latest “Fascinating IP” award goes to the golf club disclosed in USPN 7,211,006 titled “Golf Club Including Striking Member and Associated Methods.” The patent describes the invention as a golf club head having a striking member that deflects inwardly during initial contact with a golf ball and recovers outwardly as the golf ball …

Your Web Address is Intellectual Property… Choose With Care…

Everyone knows that a catchy domain name can be critical to the success of many businesses. Likewise, a poor domain can cause confusion, and even result in lost business. Additionally, a great domain name can be worth a lot of money. I recently found several funny articles about domain names and the potential of unintended meanings. As you may know, an anagram is a word or phrase made by rearranging the letters in another word or phrase. A particular class of anagrams doesn’t involve the rearranging of any letters but rather the rearranging of spaces. One classic example of this is the transformation of…

USGA Senior Technical Director, Dick Rugge, as Inventor

Mr. Rugge worked at Taylor Made for many years as vice-president of product creation and oversaw the design, marketing, research and testing of new clubs. Therefore, the obvious next step was to take a look at golf patents that list Mr. Rugge as an inventor. Pretty nice patent portfolio. Check it out…

Want to Increase Your Club Head Speed? Consider this Unique Club

Increase your club head speed and the ball should go further. Simple, right? Just swing harder or reduce the aerodynamic drag of your golf club… The problem is that whenever I increase my club head speed I usually find my tee shot on nice short grass in the vicinity of little red markers on the ground. Some people refer to the area as the women’s tee box. Perhaps I should be looking into reducing the drag of my club head. Maybe the golf club disclosed in US Publication No. 20070093315 will solve all my problems …
