Above is a counterweight trebuchet, a catapult configured to throw a load, such as one or more projectiles, toward an intended target. The trebuchet includes a sturdy frame f and an arm a. Arm a has an end e1 counterweighted by a weight w and an opposed end e2 including an attached sling s configured to adjust between load securing and releasing positions. Frame f extends upwardly from its substantial base b to arm a mounted to swing about a fulcrum p over an underlying ground surface. The arm’s a length between fulcrum p and end e2 is greater than the arm’s a length between fulcrum p and end e1 for leveraging purposes. A hoist h operates to swing arm a about fulcrum p to raise counterweighted end e1 and lower end e2 to a cocked position. Arm a swings about fulcrum p under the influence of counterweighted end e1 from the cocked position of end e2 to a launch position of end e2 upon releasing arm a from hoist h. Sling s swings with arm a accelerating a load secured by sling s when arm a swings from the cocked position of end e2 to the launch position of end e2. Releasing the load from sling s when end e2 reaches its launch position throws the load toward the intended target.
The Ethos of a Patent Claim Drafter: Focus on a novelty, the new over the old, field-specific context, and only as much old as required to support the new.
Assuming a point of novelty of this trebuchet is the sling, below is an example of two independent claims drawn to this trebuchet.

"Our company has worked with a number of patent attorneys and were so pleased when we began working with Parsons & Goltry nearly a decade ago. Mike Goltry's knowledge and attention to detail has enabled us to have numerous products patented and trademarks registered. We highly recommend this Law Firm."
"Michael Goltry is the most professional, honest and effective patent attorney whom I ever met in my 40 year professional engineering career. I started to work with him over 20 years ago and plan to work indefinitely."
"Mr. Goltry took a provisional patent that we'd filed ourselves, and quickly and professionally turned our innovation into U.S. and foreign applications. His [patent claims] were a thing of beauty, and I was amazed by how deftly he countered the inevitable office actions. His language held up, and the U.S. Patent just issued. He was easy and efficient to work with, and his fees were remarkably reasonable. We're not planning to go anywhere else, ever."
"I applied for a patent through Parsons & Goltry. After being on the docket for 2 years at the USPTO, I received notification that my patent request had been denied. Michael Goltry contacted me immediately to review my options. After I informed him of my decision to move forward, he filed a response to the USPTO. In his response he got the examiner to fully understand the claims in the patent application and the "denied" decision was reversed. I was able to secure and receive a "patent granted" decision. Thank you, Michael Goltry."
