Latest patents from TMag, Callaway, Ping and Titleist
It’s been a month since we last looked at what the major OEMs have been up to in the world of patent filings. So it seems like a good time to see what the best and brightest (or at least best paid) in golf’s R&D have been up to.
This month: A sampling of recent filings from Callaway, TaylorMade, Ping, and Titleist along with traditional patent drawings, which a comment on a previous edition in this series referred to as “napkin sketches.”
Without further ado, brief descriptions and corresponding napkin drawings.
Callaway/Odyssey putter

On behalf of subsidiary Odyssey, Callaway applied for a putter with a “low head center of gravity and a high MOI.” According to the filing, the putter features both low-density and high-density layers. In addition, the layers appear to be joined by a urethane dampening layer, and the heel and toe of the putter are outfitted with tungsten weights.
It appears that this putter will also include the white/black components the company has been including in their designs in recent years.
Overall, the putter appears similar to the flatsticks in the White Damascus family in terms of design and weighting, but presents elements of the Versa family of putters as well.

TaylorMade iron

TMag has filed a patent “coated golf club head/component,” which features an “outer layer of titanium carbide, typically comprising at least forty percent…carbon content.” One would assume that the outer layer is designed to enhance distance, and indeed the multi-layer structure is engineered toward this end.
The filing indicates that the club will possess multiple layers. Further, it states, the “titanium carbide layer is durable and can provide the golf club component with a desired aesthetic appearance, such as a black color.”
Certainly, this could be a red herring. However, the document seems to suggest that TaylorMade, with its penchant for pushing boundaries, could be working on a (at least partially) black iron.
TaylorMade fairway wood

California-based TaylorMade has also been granted a patent for a “fairway wood center of gravity projection.” The club will look something like the above, with three weights near the front of the sole of the club.
Not surprisingly, with the design the company is pursuing “club heads for a fairway wood that at least one of a high moment of inertia, a low center-of-gravity, a thin crown and a high coefficient of restitution.”
Yes. That ought to do it.
Ping hybrid

Here’s a hybrid club Ping is working on referred to as a “club head with deflection mechanism and related methods.” The intention of the mechanism seems to be to make it easier to hit the ball on the center of the club face (reportedly, that’s not a bad place to consistently make contact).
The filing also features sketches of a fairway wood with similar characteristics.
Founder Karsten Solheim’s company is also working on an iron that looks like this, which looks to be part of a complete set of clubs with variable constructions.

Titleist fairway wood

Fairhaven, Mass-based Titleist filed a patent for a “golf club head with flexure.” According to the filing, “the flexure provides compliance during an impact between the golf club head and a golf ball, and is tuned to vibrate, immediately after impact, at a predetermined frequency.”
Thus, the design, which looks rather progressive compared the Titleist’s more traditional offerings, seems also to be at the fore of the trend toward enhanced feedback. And it doesn’t take an R&D whiz to realize that the face is likely hotter because of the flexure/increased face flex.

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

taylor made will announce that they are building a solid metal head with no slots and it will come in only black and the sheep will run and buy it because the ad will talk about pure mass being better than flex.

Introducing the taylormade SCREW”R” fairway wood its got to be atleast 34 yards longer by now . The titleist and ping club looks like every adams club and the rbzs the slots in the woods and hybrids do help with consistency i feel if nothing else , but if every one is doing it there must be something in it.

If a “gimmick” introduced by Taylormade (meaning slot technology) is then copied by the arch-conservative Titleist, does it not cease to be a gimmick and become an innovation?

Introduced by Adams, not TaylorMade – at least in recent metalwood history. In reality there have been slots in woods for years, see Hogan, Wilson, etc going way back in the day. :).

Correct, Wilson made an iron in the 70’s called the “Reflex” iron. It was the forerunner to everything made today by Taylor, Callaway, Adams, etc. It was probably crude at that time but it was the first iron with that technology. It was a cast club, not forged and I am not sure what became of it’s legacy.

I hate to see Titleist go down the path of gimmicky crap, but I guess to keep up with their competitors they have to. It’s a shame so many people buy into it. I’ve put my old (by today’s standards) 904f up against many of the newest fairway woods on the market and it still outperforms them all. No adjustability, no moveable weights, no velocity slots, just a nice traditional pear shaped head that’s well balanced and gives me great distance and the perfect trajectory.

I don’t care how gimmicky/techie it is as long as I can’t see those bits. And it looks like I can see all that on this Titleist. Boo!

I am a betting man and I bet that TaylorMade is finally going to bring the technology that they have in the face of the Gloire driver to an iron and bring it to the states sometime in the future.

The iron from taylormade i believe will be the SLDR irons. More forgiving and a hotter face.

Yup, they’re coming out with SLDR and SLDR S next. Irons will be called SLDR
