Year: 2008

As you know, Golf-Patents.com has repeatedly used putter design patents to test your knowledge of putters (click here to satisfy your hunger for putter patent posts). The figure below come from a US putter design patent that issued recently to a major producer of clubs. Can you identify the brand of putter?

Hybrids, iron-woods, rescue clubs, utility clubs, ….. whatever you call them, it seems as though their popularity is growing every year. The following figures come from a design patent
directed to a hybrid. Can you identify the manufacturer?

I recently saw a post on a golf blog about the UROClub and chuckled (sorry, can’t recall which blog it was). Then almost fell out of my chair when a few weeks later I came across a published patent application on the device. The patent application published as US Pub. No. 20080127402 titled “Urinal Apparatus Including a Simulated Golf Club” and describes the invention as….. Check out these drawings….. I know that it is probably 100 percent spill-proof, but I am not comfortable risking any spillage on my grips or bag. (Perhaps when I am older) Although, the fact that it was invented by a urologist does give the product an extra level of credibility, but $50! It would make a good gag gift for the senior golfer in your life.

I often wonder, “is there money to be made in golf training products?” There must be because the number of golf training aid patent applications is through the roof! A recent training aid patent application published as US Pub. No. 20080139332 titled “Golf Training Aid,” and describes the invention as…. The following drawings do a better job of explaining the invention….. I would try it, but wouldn’t buy it.

That is just what I said when I came across one rather unique golf club disclosed in recently published patent application US Pub. No. 20080132349 titled “Golf Club Head having Concavely Curved Face.” Check out these drawings!….. The application describes the invention as….. Do you think this club would help your game?

Check out this putter that was granted a utility patent this week….. I bet you didn’t think that was the side of the putter designed to strike the ball! The patent is USPN 7387576 titled “Golf Club,” and describes the invention as…. Would this putter ever find a place in your bag?

If you strip all the logos off a golf club head, the typical avid golfer can usually identify the manufacturer of the popular drivers… often the popular irons… and sometimes the popular
putters… but I bet that most readers cannot identify this set of irons. These drawings come from a design patent issued to one of the popular club makers. Can you identify the brand?

An interesting golf cart patent issued today combining two loves of many people. Golf and cigars! The patent is USPN 7387127 titled “Cigar Holder for Golf Cart” and describes the invention as….

A few weeks ago a Callaway design patent issued that made me scratch my head and say “what club is that…. I don’t immediately recognize it so it must be one for the ladies or the juniors.” Well, I still don’t know, but it definitely has a sole configuration unlike any clubs they currently have in the US market. It may the design of new product offering. The patent is USPN D569941 titled “Golf Club Sole.” Check out this sole design…..

Earlier this week I posted about a Taylor Made patent application disclosing a pretty radical driver with fins. Well, Callaway has stepped up to the plate this week with a patent application disclosing a driver that is even more radical! Check out this Callaway driver design!….. The published patent application that may be giving us a sneak peak at future Callaway drivers published yesterday as US Pub. No. 20080139336 titled “C-Shaped Golf Club Head.” So, will the finned Taylor Made driver or the C-shaped Callaway driver make it to market first?

Would you ever expect to see the term “drag chute” used in a golf training aid patent? Well, check out the description and drawings of the invention found in USPN 7384344 titled “Physical Conditioning Aid for Golfers”…..

Check out this putter that was granted a utility patent yesterday…. (figures)…. The patent is USPN 7384345 titled “Golf Putter with Rotary Disc Alignment Aid,” and describes the invention as…. I would be willing to give this putter a try.

I never thought I would live to see the day that a Taylor Made driver had fins! OK, I haven’t actually seen fins on a Taylor Made driver; just drawings of a finned driver from a Taylor Made patent application. If a finned Taylor Made driver does make it to market I am sure they will make it look cool and will overwhelm golfers with enough marketing hype that we all end up believing that we can’t live without it. The published patent application, that may be giving us a sneak peak at future Taylor Made drivers, published last week as US Pub. No. 20080132355 titled “Golf Club Head Having Ribs.” Check out these drawings……. Can you believe it?

The figures below come from a driver design patent that recently issued to Karsten. I bet you can’t identify this PING driver!…. (figures) ….. You can click here for the answer, and click here to check out USPN D569937 titled “Golf Driver Head.”

Last week an interesting training golf grip was granted a design patent, namely USPN D569939 titled “Golf Grip.” Check out these figures….. Frankly, I think I would be too worried about breaking a wrist or finger to concentrate on the correct hand position.

Check out the golf glove contained in USPN D570056 titled “Golf Glove.”…… Interesting glove, but I am not sure what aspects are ornamental versus functional (a key aspect of design patents versus utility patents).
……

Few golfers ever consider the time and effort that has gone into the design of the golf glove they use and abuse until it is so worn, tattered, and sweat stained that it is callously
discarded in the nearest trash can. Perhaps this post will help you “appreciate” your golf glove as a unique piece of golf technology designed to improve your game, rather than simply that crumbled
up crusty piece of leather and Velcro that is stuffed into your golf bag after the round. Acushnet recently had an interesting golf glove patent application publish as US Pub. No. 20080109934 titled “Vibration Reducing Golf Glove.” The title sounds pretty good, right? The application describes the invention as….. Now, next time you put on your trusty golf glove, look at it affectionately as a piece of technology engineered to improve your game, not just a blister preventer!

This week a fascinating golf shaft design patent issued. The patent is USPN D569940 titled “Golf Shaft.” Check out this drawing….. Interestingly, the design patent also covers a flag pin…… So, would you be willing to try this shaft?

Last week Dynamic Brands, LLC (doing business as The Bag Boy Company) brought a declaratory judgment action against Sun Mountain Sports regarding Sun Mountain’s patent USPN 7131534 titled “Golf Bag and Strap System.” Click HERE to check out the patent, and click HERE to read the Complaint. It appears the dispute began when Sun Mountain’s counsel sent a letter (click HERE to read) to Bag Boy alleging infringement of the ‘534 patent. Bag Boy then responded with a polite email to Sun Mountain (click HERE to read) inquiring if Sun Mountain would license the patent if indeed Bag Boy was stepping on the patent. In response, Sun Mountain had their attorneys make it clear that licensing the patent is not an option, Sun Mountain wants Bag Boy’s sales of these particular straps to cease immediately and any inventory must be destroyed (click HERE to read). Not surprisingly, Bag Boy then filed a Declaratory Judgment action seeking a declaratory judgment that Bag Boy does not infringe the patent and that the patent is invalid (click HERE to read the Complaint), and Bag Boy sent Sun Mountain a nice letter explaining Bag Boy’s position and letting them know that they have been sued (click HERE to read). Gone are the days of the cease and desist letter; yet some people refuse to accept it, or don’t care about controlling the location of litigation. The patent describes the invention as…..

This week a wedge design patent issued on a wedge that is more identifiable than a classic Cleveland or Vokey wedge. You should recognize the wedge found in USPN D569932 (titled “Golf Club Head”) from the ton of advertisements in golf magazines……

Everyone has heard the marketing hype regarding dual durometer golf grips, but what about putter face inserts? This week PING (actually Karsten) was granted a patent for just that. The patent is USPN 7374499 titled “Golf Club Head with Dual Durometer Face Insert” and describes the invention as…..

Ahh, more golf industry patent infringement litigation; the stuff that makes attorneys smile. The PING Rapture is the latest target of patent infringement allegations. Yesterday VyaTek Sports, Inc. sued Ping, Inc. and Karsten Manufacturing Corporations for allegedly infringing two of VyaTek’s patents. Click HERE to read the actual Complaint. The patents-in-suit are USPNs 7207354 and 7314067, both titled “Design and Manufacturing Method for Multi-Material Tube Structures.” The patents describe the invention as…..

On Tuesday an interesting utility patent issued on a pretty popular putter design. OK, “pretty popular” may be a stretch, but it is a pretty “unique”, or distinctive, putter that true
putter aficionados will likely recognize. The patent is USPN 7374497 titled “Golf Putter Head With Visual Alignment System.” Do you recognize the putter brand?….. (figures) …… Click here for what is probably the answer. I say “probably” because the patent is assigned to Sienna Sport Limited of Northern Ireland, not the company that owns the linked website. At first blush the product and the patent seem so similar that I suspect there is a licensing or distribution agreement between the two companies. The patent describes the invention as…..

Marketing types always say…. it is all about brand recognition. I suppose “brand recognition” is slightly different than “golf club design patent drawing recognition,” (ok, more than slightly) but
they are not entirely unrelated. The following drawings come from a driver design patent that issued yesterday to one of the big guys. Do you recognize this club?…..

I bet that at least 77% of golfers will not recognize this driver. The following drawing comes from a driver design patent that issued recently to one of the big guys. Do you recognize
this club?…..

A truly playable lighted golf ball…. can it be made? I have my doubts. Last week a lighted golf ball patent application published in which the inventor discloses his view of the ideal
lighted golf ball. The application published as US Pub. No. 20080108454 titled “Golf Ball Containing Photoluminescent Material and a Light Source,” which describes the invention as….. Interesting, but my gut tells me that there are a few technical challenges that the inventor will have to overcome.

An interesting patent issued on Tuesday that is supposed to assist golfer in reading greens. I reviewed the patent and thought to myself….. “I would give those glasses a try.” The
patent is USPN 7370960 titled “Method and Apparatus for Viewing a Golf Putting Green” and describes the invention as…..

I am not sure what to say about this golf club patent application titled “Golf Club, Jetdrv Driver for Increased Distance and Accuracy;” other than to say that it is interesting (and it
did not result in a patent being issued). The application published as US Pub. No. 20050032584 and contains the following figures….. The application describes the golf club as follows….. Do you believe it?

I recently stumbled across a rather interesting putter utility patent that classic car lovers will appreciate. The patent is USPN 5961398 titled “Golf Club Head Apparatus” and looks like the rear of a 1957 Chevy. Check out this putter…. Frankly I am surprised that the inventor obtained a utility patent on this putter since it seems as though the unique attributes are the nonfunctional ornamental design of the putter rather than anything having to do with the utility. Regardless, it is a pretty cool putter!……

Recently a golf related patent application published with the title “Handheld Device for Determining Golf Ball Trajectory for Putt or Chip Shot and Method Therefore;” namely US Pub. No. 20080102989. I am willing to read anything that has a shot at improving my putting, so I jumped right in to see if I felt this invention could help my game. The basic invention looks like this….. So how does it work? Well, the following paragraphs explain the concept with respect to the drawings below….. So, do you think this golf invention could help your putting? I will …..

Recently a patent application published with the title “Golf Cart Glove Holder-Dryer” (US Pub. No. 20080083131). OK, interesting title…… you have my attention. The application goes on to describe the invention as….. Not the best description, but the following drawing tells the rest of the story…… Good idea! I would buy a few if I owned my own golf cart.

As you know, Golf-Patents.com has repeatedly used golf club design patents to test your knowledge of golf clubs. Now for the ultimate test….. a chipper. Who in the world can identify
the maker of a chipper? Well, probably only people that actually play this brand; but give it a shot. Can you identify the brand of this chipper?

I love reading patent applications directed to inventions designed to eliminate lost golf balls. Such inventions generally appear very impractical, expensive, or involve technology that would be difficult, or impossible, to incorporate into a golf ball; which is what I expected to find when reading a recently published patent application (namely, US Pub. No. 20080061236 titled “Device for Assisting in Finding an Article”). Upon reading the patent application I was blown away because I found myself saying “this doesn’t seem that impractical, in fact it might be a decent idea and I would consider buying one if it were under $50.” The patent application describes the invention as…..

Interesting golf tee inventions do not come along every day. Fortunately last month a patent application published that revealed an interesting tee design. Admittedly, it is not
necessarily a golf tee that I would buy or use, but it is pretty cool nonetheless. The application published as US Pub. No. titled “Self-Righting Golf Ball Tee” and the following drawing says it all…..

This week an interesting patent issued to a golf company that I did not think was even still in business, namely Pixl Golf (click here for an article on the origins of the company, and click here for a 2003 article on Pixl irons). The patent is USPN 7364513 titled “Golf Club Head with Inserts for Impact Face,” which describes the invention as….. Check out these drawings that nicely illustrate the concept…… Interesting concept, but is it enough to revitalize Pixl Golf?…..

Typically when a golf club design patent issues to one of the major equipment players I expect to open it and see a club design that they introduced months ago, but not today. The US Patent and Trademark Office issues patents every Tuesday. Therefore, much of my Tuesday morning is spent reviewing the latest golf related patents, which is always entertaining but rarely do any of the patents really surprise me. Well, today I was surprised by a design patent that issued to Acushnet (a company known for great products under the Titleist and Cobra brands, but not known for wild club designs). Just check out these drawings….. Could this be the next new Titleist or Cobra driver? I can’t wait to see if this design makes it to market……

If you strip all the logos off a golf club head, the typical avid golfer can usually identify the manufacturer of the popular drivers… often the popular irons… and sometimes the popular
putters….. but rarely the fairway woods of the large golf companies. Can you identify the producer of this fairway wood?…..

Would you ever guess that a patent titled “Symbolically Reinforced Golf Club Head” would contain this iron design? Bling, bling….

Check out these figures contained in a golf related design patent that issued earlier this month. Can you guess what it is? (scroll way down in the post for the answer)…..

The company behind The Club Glove travel bags, which according to their website are the number one travel bags on Tour, have sued Armor Gear alleging infringement of USPN 7219902 titled “Flexible Travel Bag with Integrated Support to Protect Bag from Wear.” The Complaint alleges that Armor Gear’s Big Kahuna, Big Kahuna II, and the Rolling Sherpa IIz bags infringe the ‘902 patent. Click HERE to read the Complaint. The ’902 patent describes the invention as…..

Blogging has been slow lately. I apologize, but everyone needs a vacation once in a while. I just returned from a great trip to Palm Springs where I was fortunate to play many of the
PGA West courses. Needless to say….. it was incredible. The courses were beautiful and my game was awful after a long Ohio winter break, but what surprised me the most was the……

Interesting golf tee patents are few and far between. Fortunately, a unique golf tee patent did issue last month, although I am not quite convinced that we will see it in local pro shop any time soon. Fun to look at nonetheless! The patent is USPN 7344456 titled “Flexible Golf Tee.” Check out these drawings…..

As you know, Golf-Patents.com has repeatedly used putter design patents to test your knowledge of putters (click here to satisfy your hunger for putter patent posts). The figures below come from a US putter design patent that issued recently to a major producer of clubs. Can you identify the brand of putter?

Boy, a ton of putter design patents have issued recently! As you know, Golf-Patents.com has repeatedly used putter design patents to test your knowledge of putters (click here to satisfy your hunger for putter patent posts). Well this should be a relatively easy one…. How good are you at identifying a particular brand of putter when all the logos and trademarks are stripped off the club head? The figures below come from a US putter design patent that issued recently to a major producer of clubs. Can you identify the brand of putter?

I bet that at least 77% of golfers will not recognize this driver. The following drawings come from a driver design patent that issued recently to one of the big guys. Do you recognize this club?…..

Many golfers would be surprised to learn that majority of golf grips are patented. Some manufacturers apply for utility patents on their unique grip construction and manufacturing
methods, while others merely seek to protect the ornamental look of the grips via design patents. Recently a golf grip design patent issued on a fairly popular grip, can you identify it from the
design patent drawings?

Golf-Patents.com has repeatedly used putter design patents to test your knowledge of putter designs. For today’s test, can identify the maker and model of this putter?

Familiar with the PuttingDisc? (the website is a little rough) I saw the figures below in a patent that issued this week and thought that I had seen it before, but there is hardly a reference to it on the web (so I must have been mistaken). Oh well, further proof that it is not easy to get a golf training aid to market. The patent is USPN 7347789 titled “golf putting practice device” and describes the invention as….

As a golfer whose game fluctuates from marginal, at best, to horrible (as my playing partners will attest from my first round of 2008 that I played on Thursday), I view most training aides with a skeptical eye. After all, I have tried a lot of things and the only thing that seems to help my game is a lot of time on the range and a lot of rounds. Therefore, I could not believe it when this week a golf training device patent issued and I found myself saying… “not a bad idea; good for use in the backyard, especially if your neighbors won’t put up with the sound of your driver blasting balls into a practice net.” The patent is USPN 7347790 titled “golf swing training device.” The patent describes the invention as…… I describe the invention as……

Golf-Patents.com has repeatedly used putter design patents to test your putter knowledge. Today a unique golf putter design patent issued…. check out the drawing below. Can you identify the make and model?……. Click here for the answer; and click here to check out USPN D565142 titled “Golf Club Head for a Putter.”

It is hard to believe that is has been over a year since I authored a post titled “Bust Your Competitors’ Patents” regarding the patent reexamination process. Since that post many of you have probably learned a little more about the process simply by following my coverage of the Callaway v. Titleist ProV1 golf ball patent dispute. Well, recently a Request for Ex Parte Reexamination was approved by the USPTO regarding a push golf cart design patent, so I thought it would be a good opportunity to share this golf patent reexamination example with the Golf-Patents readers. Back in November a Request for Ex Parte Reexamination was filed regarding USPN D502303 titled “Golf Cart.” The golf cart in question is shown below…….

As you may recall, back in late December Nike filed a lawsuit taking on the clones (Illinois Northern District Court; 07-c-7108). Specifically, Nike’s December 18th complaint named King Sports, Inc. dba Turbo Power Golf, Hung Ying Chang, Krookedstix, Inc., and Gigagolf, Inc. as defendants. Click HERE to review the prior post. It didn’t take long for GigaGolf and KrookedStix to fold and agree to a Consent Judgment and Permanent Injunction with Nike. Click HERE to read the GigaGolf document; and click HERE to read the KroodedStix document. GigaGolf and KroodedStix agreed that they do in fact infringe the Nike design patents and agreed to stop manufacturing and selling the infringing clubs. Interestingly, KroodedStix sold a grand total of “no more than 49 clubs that infringe” the patents-in-suit! King Sports apparently has decided to fight it out and has filed an Answer to the Complaint. Click HERE to read the Answer. To no surprise, King Sports denies infringement and alleges that the patents are invalid. I am not sure I would want to be in the position of King Sports in this lawsuit, but you be the judge……

Back in the fall I authored a post about a patented putting method. Judging from the number of page views and links to the post, I suspect a lot of golfers were surprised to learn that a putting method could be patented; although, let’s face it, the patented putting methods are a little on the unique side of things (to put it nicely). Needless to say, none of the top 10 players in the world took me up on my challenge from the last post:…….. Surprised? Me neither. Anyway, I thought that it was time to revisit the topic and take a look at another patented putting method… so here is USPN 7121954 titled “Putting Method and Putter.” Check out these figures from the patent:…….. So how do you describe it in words… easy, just check out this claim from the patent:…….. So, next time you are watching The Golf Channel see if you can spot any patent infringers (judging from the figures above… I doubt it).

This week Karsten (makers of PING putters) had an interesting patent application publish as US Pub. No. 2008005121 titled “Acoustically Tunable Golf Club Head.” The application describes the invention as……
Check out these figures from the application…… I hope this putter makes it to market!

Time to brush-up on your knowledge of ferrofluids, magnetorheological fluids, inverse magnetorheological fluids, and magnetorheological elastomers. Today a patent application published with the title “adaptive golf ball,” and describes the invention as a “smart golf ball.” OK, that got my attention. It just so happens I have been looking for a ball that can predict when I am going to hit it off the toe and then adjust accordingly. Well, come to find out… the ball disclosed in US Pub. No. 20080045358 isn’t quite as smart as I was hoping for. Oh well, how fun would golf really be if you were always in the middle of the fairway? The patent application describes the invention as…… What is so “smart” about this ball? Well, the following paragraphs from the application do a good job of explaining the concept……. Sound too good to be true?

A design patent issued yesterday under the title “Rocket Golf Tee,” so I just had to check it out and share it with you. Check out these figures from USPN D562420!………(drawings)…….. Interesting, but will it help your shots go any farther or straighter?

Ready to test your iron knowledge? No worries, this test should be easy for the avid golfer (or anyone with good analytical skills… i.e. there is a hint in the drawing). The figure below comes from a US golf club iron head design patent that issued this week to a major producer of clubs. Can you identify the brand of irons?……….

Every golfer has at some point suffered from a case of the shanks. I know that I do at least twice a season. Judging from number of off-set wedge related patents I would say that golfers spend a lot of time thinking about how it must be a problem with the clubs; surely not the swing! I previously posted an overview of a lot of clubs directed at curing the shanks (click HERE to read). Recently a patent application published directed to another seemingly shank-resistant club. Check out these figures from US Pub. No. 20080026867 titled “Golf Club.”…….

Last Valentine’s Day I wrote about a golf ball with heart shaped dimples (click here). Ahh, so sappy and sweet! I have been keeping a published patent application a secret just for a Valentine’s Day post; or more appropriate, I doubt anyone was looking for it. Nonetheless, the application title “Sweetheart Putter” got my attention. The following figure comes from published application US Pub. No. 20080009361……. Interesting design…. I am guessing this one will be marketed to the ladies!

Here comes the softball of the year! The figure below comes from a US golf club iron head design patent that issued this week to a major producer of clubs. Can you identify the brand of irons?…..

Marketing types always say… it is all about brand recognition. I suppose “brand recognition” is slightly different than “design patent drawing recognition,” (ok, more than slightly) but they are not entirely unrelated. The following drawings come from a driver design patent that issued today to one of the big guys. Do you recognize this club?……. So, does this club have good brand recognition?

Last week I posted about an interesting Nike patent application directed to golf clubs incorporating a fluid-filled bladder. Imagine my surprise this week when a patent issued to Fu Sheng Industrial, the world’s largest OEM manufacturer of golf club heads, directed to a remarkably similar design. The Fu Sheng patent is USPN 7326127 titled “Golf Club Head with Gas Cushion.” Check out these drawings from the patent…… Compare the Fu Sheng patent (USPN 7326127 titled “Golf Club Head with Gas Cushion”) to Nike’s published application (US Pub. No. 20080015050 titled “Golf Clubs and Golf Club Heads Having Fluid-Filled Bladders and/or Interior Chambers”). Turns out that great minds do think alike. Looks like we probably will see a club make it to market with a fluid-filled bladder.

Would a patent application titled “Mouse Putter” get your attention? It got mine. So, do you putt mice with it or what? The application published as US Pub. No. 20080009367 titled “Mouse Putter.” Check out this putter design……

OK golfers, how well do you know your drivers? These drawings come from a driver design patent that issued Tuesday to a major club maker. Do you recognize this club?….. You can click here for the answer, and click here to check out USPN D561284 titled “Golf Club Wood Head.”

I didn’t think last week’s post regarding the 3-wheeled bag-riding golf cart could be outdone, but boy was I wrong. Last week an amazing patent issued titled “Collapsible Golf Scooter Cart Having Fold Out Balance Wheels” (USPN 7322434). A what? A golf scooter! Check out this drawing of the scooter……. How would you feel cruising around the course on this beauty?

The Golf-Patents blog has tested your knowledge of iron club head design in the past. Today, let’s see if you can identify another set of irons. For frequent readers of this blog, I rate the level of difficulty of this one as ridiculously difficult. Good luck.
The figures below come from a US golf club iron head design patent that issued today to a major producer of clubs. Can you identify the brand of irons?….

If I searched patents for the term “fluid-filled bladder”… the last thing I would expect to find would be a patent application for golf irons! But that is exactly what I stumbled across recently. More specifically, it was a published patent application directed to a Nike Slingshot design containing a fluid-filled bladder. The application published as US Pub. No. 20080015050 with the title “Golf Clubs and Golf Club Heads Having Fluid-Filled Bladders and/or Interior Chambers.” The application describes the invention as…… So what fills the fluid-filled chamber? The application states that it could be filled with air, inert gases, or liquids. Check out these figures from the application…….
It will be interesting to see if a patent issues from this application, and whether such a product ever makes it to market…..

Another golf invention that words just don’t do justice! Check out these figures……… The drawings come from a recently published patent application US Pub. No. 20080023236 titled “Combined Golf Caddie And Golf Cart.”
Am I nuts, or wasn’t there some problems with the roll-over potential of 3-wheel ATV’s on uneven terrain? Surely that won’t be an issue for this invention….. (I mean it looks pretty stable, right?)

I knew that title would get you interested… but seriously, this post may contain the next hot new golf shoe design and perhaps a glimpse into future FootJoy offerings. Yesterday Acushnet was granted 6 golf shoe design patents. The patents are USPN’s D560338, D560339, D560340, D560341, D560342, and D560343; all titled “Golf Shoe Upper.” Recognize any of these styles?…..

On Friday Stroke Solutions, Inc., maker of the SuperStroke putter grip that KJ has made famous, filed patent infringement lawsuits against Tacki-Mac Grips, Inc. and Energy Grip, Inc. in the Eastern District of Wisconsin. The actual Complaints filed with the court do not contain much information, but you can check them out HERE and HERE. The patent at the center of the dispute is USPN 6626768 titled “Putter Grip.” A few figures from the patent are found below….. I will keep you posted on this gripping patent infringement lawsuit….
