1004 Exhibit: US Patent Publication No 20070275791 Shear

Document PGR2018-00074, No. 1004-4 Exhibit - US Patent Publication No 20070275791 Shear (P.T.A.B. Jul. 6, 2018)
The present invention is directed towards a golf club head having integrally incorporated twisted face angles which are selected to match a particular golfer’s swing speed.
For example, the golfer hits a variety of drivers having variations in head and shaft characteristics, and golf balls of different construction and performance levels are measured.
Cameras monitor the golfer’s launch conditions by tracking the movement of a cluster of light emitting diodes attached to specific locations on the golf ball.
[0013] The invention also provides for a method of fitting a proper club to a particular golfer by choosing second and third tangent angle values which are selectively based upon a user’s swing speed.
[0023] While it would be obvious that the twisting effect of the present invention will cause the loft angle to change very slightly from the heel to the toe, any drop in distance will be almost negligible (approximately 1-2 yards).

In addi tion, it is proposed that bulge radius is determined in such a way that it fulfils a predetermined conditional equation con cerning a moment of inertia (for example, Patent Document 4).

[0058] Note that, in the present measurement, it is neces sary to hit the ball with a constant head speed and orbit and precisely at a desired position of the face part 2.
[Equation 16] [0068] Therefore, in the state shown by FIG. 4, total num ber of revolutions Nt2 (rpm) around the first horizontal axis Lx to be generated on the ball is a sum of number of gear Page 9 of 11

1008 Exhibit: US Patent No 8,388,459 Chuck

Document PGR2018-00074, No. 1008-8 Exhibit - US Patent No 8,388,459 Chuck (P.T.A.B. Jul. 6, 2018)
This causes many golfers to rely on a false sense of security, provided through the use of a tee or tuffs of grass, which positions the golf ball in an elevated relationship to the ground surface.
In some methods of use, such lower face portions can provide a generally downward striking force on the golfball to produce an undesirable trajectory and distance 60 through which the golf ball travels.
In such embodiments, a lower face portion 34 is shaped to provide a generally downward striking force on the golfball, producing an undesirable trajectory and 60 distance through which the golf ball will travel.
According to standard golf ball sizes used today, it is antici pated that the lower edge of the striking face 32, in some 35 embodiments, may be spaced from the sole 26 of the club head 18 by a distance of approximately 0.9 inches.
Accordingly, various methods of employing the training golf club 10 will have the player move the elongated shaft 12 so that the lower edge portion of the striking face 32 is positioned at least just below a horizontal plane "X" extending through the middle of the golfball40.

1005 Exhibit: US Patent No 7,887,431 Beach

Document PGR2018-00074, No. 1005-5 Exhibit - US Patent No 7,887,431 Beach (P.T.A.B. Jul. 6, 2018)
(73) Assignee: Taylor Made Golf Company, Inc., Carlsbad, CA (US) (*) Notice: Subject to any disclaimer, the term of this patent is extended or adjusted under 35 U.S.C. 154(b) by 160 days.
In particular embodiments, the connection assembly includes a removable hosel sleeve that allows a shaft to be supported a desired predetermined orientation relative to the club head.
For example, the manner in which rotational 5 movement between the constituent components of a club head shaft interconnection is restricted must have sufficient load-bearing areas and resistance to stripping.
This variety is driven, in part, by the wide range in physical characteristics and golfing skill among golf- ers and by the broad spectrum of playing conditions that a golfer may encounter.
In general, reducing the thread diameter increases the ability of the screw to elongate or stretch when placed under a load, resulting in a greater preload for a given torque.

1003 Exhibit: Declaration of Steven M Nesbit, PhD Nesbit Decl

Document PGR2018-00074, No. 1003-3 Exhibit - Declaration of Steven M Nesbit, PhD Nesbit Decl (P.T.A.B. Jul. 6, 2018)
I have been retained by the law firm of Ballard Spahr LLP, who represents Parsons Xtreme Golf, LLC (“PXG”) to provide expert testimony in support of PXG’s Petition for Post-Grant Review of U.S. Patent No. 9,814,944 (the “Petition”), filed concurrently with this Declaration.
Claim 11 then recites various reference points such as a center face location and vertical and horizontal planes that are used for defining the roll and bulge contours (highlighted in blue).
For example, in defining a “1° twist” and “2° twist”, the specification explains that the terms are “defined as Declaration of Steven M. Nesbit in Support of PGR of U.S. Patent No. 9,814,944 the total face angle change between ... two critical point locations.” (Ex. 1001, 10:28-30.)
I have been told that this test poses the question as to whether there is an express or implied teaching, suggestion, or motivation to combine prior art elements in a way that realizes the claimed invention, and that it seeks to counter impermissible hindsight analysis.

1002 Exhibit: File history of US Patent No 9,814,944 Application No15199,603

Document PGR2018-00074, No. 1002 Exhibit - File history of US Patent No 9,814,944 Application No15199,603 (P.T.A.B. Jul. 6, 2018)
This location is found by utilizing the USGA Procedure for Measuring the Flexibility of a Golf Clubhead, Revision 2.0 published on March 25,2005, herein incorporated by reference in its entirety.
Alternatively, the striking surface of an actual golf club can be laser scanned or profiled to retrieve the 2D or 3D contour before implementing the above measurement method.
In the event that the laser scanning or CAD methods are not available or unreliable, the face angle and the loft of a specific point can be measured using a "black gauge" made by Golf Instruments Co. located in Oceanside, CA.
Alternatively, if a radius is not easily obtainable in a computer model, a 127 mm curvature gauge can be used to detect the edge of the face of an actual golf club head.
Thereore utilizing the horizontal and vertical band method of measuring LAo L1 and FA o L1 within a quadrant eliminates any undue influence of a specific bulge and roll curvature.

These dimensions are measured on horizontal lines between vertical projections of the outermost points of the heel and toe, face and back, and sole and crown.
This location is found by utilizing the USGA Procedure for Measuring the Flexibility of a Golf Clubhead, Revision 2.0 published on Mar. 25, 2005, herein incorporated by refer ence in its entirety.
Of course, the above method can be imple mented in measuring the direction of a localized curvature provided in a CAD software platform in a 3D or 2D model, having a similar outcome.
Alternatively, if a radius is not easily obtainable in a computer model, a 127 mm curvature gauge can be used to detect the edge of the face of an actual golf club head.
Therefore utilizing the horizontal and vertical band method of measuring LAo ll. and FA o ll. within a quadrant eliminates any undue influence of a specific bulge and roll curvature.

ieee ceeteceeeeeneeeeteneeees 473/324; 473/330 The present invention is directed towards a golf club head having integrally incorporated twisted face angles which are selected to match a particular golfer’s swing speed.
This data is then recorded and analyzed using complex mathematical models which are able to calculate, among other things, the distance that a golf ball travels when struck off the tee by the golfer.
[0023] While it would be obvious that the twisting effect of the present invention will cause the loft angle to change very slightly from the heel to the toe, any drop in distance will be almost negligible (approximately 1-2 yards).
This will claims are intended to cover all changes and modifications allow off-center hits that are either high or low to be of the preferred embodimentof the invention, herein chosen compensated for the “gear effect” regardless of the swing for the purpose of illustration, which do not constitute speed.
