Latest patent filings: Cobra, Ping pursuing slots
A new year, a new batch of patent filings: It’s time to take a look at what the major OEMs are working on.
Last time, we saw TaylorMade experimenting with multi-layer driver face, Callaway toying with some very interesting adjustable irons, and Ping working on highly adjustable irons.
In this edition, we’ll take a look at some of the avenues TaylorMade, Titleist, Nike, Cobra, and Ping are exploring.
TaylorMade: Pursuing aerodynamic heads
In a filing for a patent “high volume aerodynamic golf club head” TaylorMade’s designers seem to be turning their eyes toward (you guessed it) aerodynamics in driver head design.

As the filing states:
“In the past the aerodynamics of golf club heads were studied and it was found that the aerodynamics of the club head had only minimal impact on the performance of the golf club.
Golf club designers pay little attention to the aerodynamics of these large golf clubs; often instead focusing solely on increasing the club head’s resistance to twisting during off-center shots.”
TaylorMade also filed a patent for the design below.

The company lays out the thinking behind the triangular design in an interesting couple of paragraphs:
“Often, golf club manufacturers are faced with the choice of increasing one performance characteristic at the expense of another. For example, the shape and size of some conventional golf club heads approach the maximum envelope dimensions in an attempt to increase the moments of inertia of the heads. Such designs, however, most likely require a decrease in the face size, or ball striking surface area, in order to comply with the USGA regulations. As another example, some conventional golf club heads have an increased face size in an attempt to optimize the ball striking surface of the golf club head. Such golf club head designs, however, typically have decreased moments of inertia.
Golf club designers and manufacturers have struggled to design golf club heads having increased moments of inertia while maintaining other desirable golf club head characteristics and abiding by the USGA regulations.”
Titleist: A progressive CG iron set
Fairhaven, Mass.-based Titleist is working on a set of progressive irons, per a recent filing. The irons feature “a progressive center of gravity allocation” in order improve launch angles.

Nike: A new golf ball
Nike is working on some new pellets. It’s always difficult to determine exactly what a company is shooting for in a golf ball patent filing, because of, well, language like this:
“A thermoplastic multi-layer golf ball has a core center having a diameter from about 21 mm to about 29 mm and including a first thermoplastic material having a first flexural modulus of less than about 15,000 psi, a core layer disposed radially outward from the core center with a thickness of at least about 4 mm and a second thermoplastic material having a second flexural modulus of up to about 15,000 psi that is greater than the first flexural modulus, and a cover disposed radially outward from the core layer. The cover comprises a third thermoplastic material having a third flexural modulus. The first thermoplastic material and the second thermoplastic material each includes an ionomer resin, and these ionomer resins may be the same as or different from each other.”
Anyway, here’s the ball:
Cobra: Channeled woods
In a filing that includes actual photos, Cobra is putting forth woods with a recessed channel.
However, as Cobra points out, there is a potential problem with “channeled” clubs. The company lays out the perceived problem and their solution in the section clipped below.
“During a high speed drive, the ramped portion of the sole may distribute and neutralize torsional stresses, dampening unwanted and unpredictable twisting that can be introduced or amplified by prior art channel structures.
“One insight of the invention is that adding an elastically deformable channel to a driver head can destabilize the structure, allowing the club head to twist, shear, or compress non-uniformly and transfer momentum non-uniformly to the strike face during the down stroke of a high-speed drive or at impact.
“Thus a club head that includes a channel area with a groove that is buttressed by a shallow ramp will resist non-uniform deformation and non-uniform momentum transfer to the face with the result that shots will fly straight, and the club head will provide the full and intended benefit of a channel in the sole—a high coefficient of restitution and a large sweet spot in a club head that hits true. The channel area or groove preferably runs in a heel-to-toe direction substantially parallel to the face and close (e.g., within a few centimeters) to the face.”
Ping: Slitted (or slotted) woods
Ping looks to be getting into the slot/channel game with the design pictured below. And as the filing says “slit” or “slot” about 300 times, the technology seems to be the core of the next generation of the Phoenix-based manufacturers designs.

Why Rickie Fowler is switching to a shorter driver at the PGA Championship
In a golf world where players are looking to eke out every yard possible, usually by lengthening their drivers to add clubhead speed, there’s one player at the PGA Championship who’s going in the opposite direction. In fact, for Rickie Fowler, his goal off the tee is not about gaining extra distance or yards north to south, but rather about shrinking the misses from east to west.
Ahead of the PGA Championship and the week prior at the Truist Championship. Fowler mentioned to Cobra Tour Rep Ben Schomin that the driver didn’t quite swing feel the same as everything in the bag. As a result, and with Schomin’s suggestion to try and sync everything up with the big stick, Fowler decided to test out a shorter length shaft.
“He’s been at 45 (inches), and he’d been at 45 for a few weeks, 44 1/8 (inches) is really is where he is been living really for the most part, for the last couple of years, and is where he is been comfortable,” Schomin told GolfWRX. “It just felt like it was a little long and loose on him.”
Interestingly, Fowler ranks 40th in Driving Accuracy this year on the PGA Tour. It’s his most accurate season with the driver since the start of the decade. But sometimes for players, feel is more important than statistics.
“It was really more of a trying to get the swing to feel the fluidness from club to club to club to try to get it to feel the same,” Schomin added. “And so we took it down to 43 and a quarter, and it was a touch of a ball speed loss, just based on that overall club head speed. But honestly, he squared it up probably a little better. The right miss wasn’t nearly as far. So really, overall down-range dispersion tightened up a fair amount, and he felt confident in swinging it.”
The change in length had Fowler’s caddie, Ricky Romano, beaming at how well he had driven during Tuesday’s practice round at Aronimink. So much so, he was asking Schomin not to suggest changes anymore.
Fowler’s shaft-shortening is one of a few driver adjustments he’s made this season, and to Schomin’s credit, it’s thanks to the fact that he and the rest of the Cobra team had Fowler fit very well into three of the four heads in the Cobra OPTM lineup.
“He had three distinct drivers and the biggest decision was trying to decide which worked best at that time,” Schomin told GolfWRX previously. “He’s played the majority of the season with OPTM X, but has also played a couple of tournaments with OPTM LS. His overall driving stats have been good.”
At the RBC Heritage earlier this spring, Fowler switched drivers, changing from his Cobra OPTM X and into the Tour, low-loft Max K model that Gary Woodland used to win just a few weeks prior.
Now for the PGA Championship, Fowler’s back in the X head, but still using the UST Mamiya LIN-Q PowerCore White 6TX shaft, just a little bit shorter.
“Will he stay there? I’m not sure,” Schomin added. “Could we end up say at like 43 and 7.5 (of an inch). If it’s giving him the same feel of consistency through the bag, then I think we might end up just a touch longer. But if he likes where he is at, he’s confident where he is at, that’s really all that matters.”
If there’s more testing, though, just don’t tell his caddie.

GolfWRX Launch Report: 2026 Titleist GTS drivers
What you need to know: As is customary for the Fairhaven-based company, Titleist officially announced today that its GTS drivers are headed to retail, following a successful tour release. The GTS2, GTS3, and GTS4 drivers will be available in golf shops June 11.
Since debuting at the Texas Children’s Houston Open, the new GTS lineup has quickly gained traction on the PGA Tour, with more than 50 players already making the switch to a GTS2, GTS3, or GTS4 driver. Among them are Justin Thomas and Jordan Spieth.

Justin Thomas’ Titleist GTS2 driver (Greg Moore, GolfWRX)
According to Titleist, the GTS series builds upon the performance foundation established by the GT Series, while introducing several major technological advancements, including a new Split Mass Frame construction, refined aerodynamics, and an updated Speed Sync face design.

2026 Titleist GTS drivers: What’s new, key technology
Split Mass Frame and thermoform body
At the center of the new GTS lineup is a redesigned internal structure: the Split Mass Frame. This technology works with a full-thermoform body made from Titleist’s Proprietary Matrix Polymer (PMP), a lightweight composite that enables engineers to reposition mass more efficiently throughout the head. Compared to the previous GT generation, GTS drivers feature nearly double the PMP material, increasing from 13 grams to 26 grams, while maintaining the sound and feel preferred by better players.
The weight savings from the thermoform construction allowed Titleist engineers to strategically separate mass placement inside the head. Specifically, more weight is pushed rearward to improve stability and forgiveness, while additional mass is positioned low and forward to optimize speed, launch, and spin.
In short, golfers are able to maintain ball speed and consistency across both centered and off-center strikes.

Faster aerodynamics
Titleist also refined the aerodynamic shaping of the GTS heads to help players generate more clubhead speed.
The tails of the new GTS2 and GTS3 heads have been raised compared to previous models, helping airflow stay attached to the crown and sole longer during the swing. According to Titleist, the improved airflow reduces drag and increases speed without affecting launch conditions or center of gravity placement.
Typically, aerodynamic gains can compromise forgiveness or launch characteristics, but the weight savings from the Split Mass Frame allowed engineers to preserve preferred CG locations.

New Speed Sync face
The new Speed Sync Face design is engineered to improve ball speed retention across a larger portion of the face. A reinforced perimeter structure helps maximize face deflection and COR on centered strikes, while the upper portion of the support ring is opened up to increase speed on high-face impacts, a common strike location for many golfers. The face also features a variable thickness design to preserve speed and performance across a wider impact area.
Expanded adjustability
Each GTS model includes a dual-weighting system to fine-tune launch, spin, and shot shape more precisely than previous generations. GTS2 uses interchangeable forward and aft weights, while GTS3 and GTS4 combine a rear weight with an adjustable forward track weight system.
Tour-inspired face graphics
The new lineup features redesigned high-contrast face graphics to improve alignment and framing at address, according to Titleist. Sharp visual lines are designed to make it easier to center the golf ball and to perceive loft more easily at setup.

Additional model details
GTS2

- The GTS2 is the most forgiving model, designed for golfers seeking maximum stability and consistent speed across the face.
- It produces high launch with mid spin and features a larger, confidence-inspiring profile behind the ball.
- Standard weighting includes an 11-gram forward weight and a 5-gram rear weight, with additional fitting configurations available.
GTS3

- The GTS3 is aimed at players who want more control over launch, spin, and shot shaping.
- Compared to GTS2, the GTS3 offers lower launch and spin while featuring a more compact profile and deeper face design preferred by many stronger players.
- The head features an adjustable forward-track weight system to further fine-tune center of gravity placement.
GTS4

- The lowest-spinning option in the lineup, GTS4 is built for golfers looking to reduce excessive spin and maximize total distance.
- Unlike previous “4” models from Titleist, the new GTS4 features a full 460cc profile that improves forgiveness and stability while retaining its low-spin DNA.
- Like GTS3, it includes a forward track weighting system for precise fitting adjustments.

What Titleist says
“When we talk about driver design, it’s never about the one feature or benefit — it’s about all of them,” said Stephanie Luttrell, Titleist’s Senior Director of Metalwood R&D. “Ball speed, forgiveness, spin stability, adjustability, exceptional sound and feel… these are all attributes that golfers care about. It’s our job to design a lineup that elevates performance across the board without sacrificing in key areas, and we feel we’ve done that with GTS.”
“We know that forward CGs drive speed with great launch and spin characteristics, but you need to be able to do that with an inertial stability that still preserves ball speed, launch and spin consistency on off-center hits,” Luttrell said. “We’ve never before been able to hit these CG positions and inertia properties at the same time, and we’re achieving that because of GTS’ construction.”
Club Junkie’s take
I feel like every time there is a new Titleist wood release, I figure they can’t outdo their previous driver. And every year, I am wrong and impressed with the performance. The GTS fits right into that narrative again, as I didn’t know where Titleist could go from GT, but they pushed the limits again, and my fitting proved the smart people there found ways to improve.
My past four Titleist drivers have been a 2 series as my swing typically requires a little height, spin, and forgiveness so I figured I would just get a new GTS2 and be on my way. During the fitting, I was impressed by the new GTS construction, its added PMP material, and the advanced adjustability on each model. My fitter, Joey, got to work putting together a GTS2 and we started there. The launch and spin were great, and the consistency on misses was very tight. My average ball speed with the GTS went up a little bit as the new Speed Sync face creates more speed away from the center.
Joey then built up a GTS3 in 11 degrees, but I figured this wouldn’t have the stability I needed for tight dispersion on my miss hits. That thought was quickly erased after a few shots, and I really liked the more center start line and reduced draw on the misses I was seeing. We tried a few different settings and shafts to dial in the details in order to get the best fit. Having a forward and rear weight in the head allowed Joey to set up the GTS3 with a heavier rear weight to keep the launch and spin up, while the Sure Fit hosel set flat created a more center start line for me. My misses were not nearly as far left, and I was really impressed with the consistency on the spin and launch when I didn’t hit it in the center.
Titleist again created a wood line in GTS that delivers improvements over previous drivers while keeping the traditional look and feel you expect. More adjustability, better off-center speed, and 3 drivers that are playable over a wider range of players should make these extremely successful in fittings.

If the first company that patented the slot did so, then how are any other companies using this same concept? And why would the patent office allow any other patents for the same concept?

It looks like the turbulators are not on the slotted club diagrams. Although not being an IP atty the patent may only be showing the item being applied for and when actually produced may incorporate the turbulators.

I play with someone who uses a TM slotted fairway… the slot picks up dirt on every practice swing, causing an annoying swing routine which involves cleaning the slot between the practice swing and the real one…
Maybe they can invent a slot that cleans itself?
My non-slotted TEE still works a lot better, BTW.

That criticism of the original Rocketblade slots has long since been corrected by subsequent models. Try keeping current. Maybe its why Titleist and now Ping and Cobra are moving into slots. Sorry Titleist calls it the “Active Recoil Channel”.

Funny how there are factual, statistical gains in distance etc from all reviews on YouTube by professionals that use launch monitors. Also strange how the slot ‘gimmick’ is being used by all of the companies, even the honest and old school Titleist and Ping. Get with the new generation of golf grandad.

hit the aeroburner last night… Brutal club. Feels really light, so much so that it feels like there is no mass behind the ball when hitting it which for me lead to shorter drives.
Ping Taking on the Slot or Slit im fine with that after seeing what it did for the Titleist this year.

Here’s the thing that I like about slotted woods, based solely on my personal experience and preferences…
You can tee the ball lower, hit it lower on the face, and still get a high-quality strike.
When I tee the ball lower, I feel like I have more control of the spin and I have less margin for error. I well remember the days of the TaylorMade R510 TP, and a thousand other similar designs, when you had to hit the ball well up into the top half of the clubface.
The TaylorMade fairway woods beginning with the Rocketballs series of a few years ago really took off with players for a reason. Those fairway woods were hitting lower on the face.
That’s just my thinking. Now a real expert can weigh in.
I am REALLY looking forward to a new slotted Ping driver design.

Not sure how I feel about so many slotted clubs entering the market, but I do like the 915 line from Titleist and the Nike Vapor and VR lines so as long as it’s done “tastefully” I guess it will be alright. But, if club manufacturers start churning out clubs that mimic the TM AeroBurner then you will have to pry my 905r from my cold dead hands!
