David Brown invented a negative ion pet hair dryer. He filed a utility patent application and soon he was granted the patent for 20 years. However, just a few months after receiving his patent, David found out that a pet-grooming business Wash and Woof is advertising the use of a new negative ion pet hair dryer. David is going to file a claim against Wash and Woof.

Dear David Brown,

I am writing in response to your inquiry regarding the infringement of your patent on the negative ion pet hair dryer.
After reviewing the matter, I recommend that you file a claim against Wash and Woof for patent infringement. In order to establish a successful claim, you must prove that Wash and Woof is using a product that is substantially similar to the one described in your patent, and that they knew or should have known about your patent at the time of the infringement.
In order to strengthen your case, I suggest gathering evidence such as advertising materials and product descriptions that demonstrate the similarities between your product and Wash and Woof's product. Additionally, it may be helpful to gather evidence of the date that Wash and Woof began using the infringing product and any other relevant information regarding their knowledge of your patent.
I also recommend that you consider seeking an injunction to prevent Wash and Woof from continuing to use the infringing product, as well as damages to compensate you for any financial losses resulting from the infringement.
Please let me know if you have any further questions or concerns, and I will be happy to assist you.

In Hamilton city there are two gas stations “Shell” and “Pioneer”. The two gas stations are engaged in a tough competition with each other, undercutting prices to attract the most customers. One day, the manager at one of the gas stations decides to schedule a meeting with the manager at the other gas station. He offers to agree on fixing price to charge customers so they can extract more profits from them. The other manager agrees, and the gas stations collectively decide to raise prices from $100 to $200. Given no other options, consumers are forced to pump gas at $200. A group of consumers want to file a claim against the two gas stations.

Dear [Client],

I am writing in regards to the matter concerning the two gas stations, "Shell" and "Pioneer," in Hamilton city. It has come to our attention that the managers of these two gas stations have engaged in price fixing, raising prices from $100 to $200 for consumers.
It is illegal for businesses to collude and fix prices, as it is considered a violation of antitrust laws. This practice can lead to harmful consequences for consumers, as they are forced to pay higher prices with no other options available.
In light of this situation, we recommend that you proceed with filing a claim against both gas stations. This can be done through a class action lawsuit, which allows a group of consumers to file a claim together against the businesses. This type of lawsuit is suitable in cases where a large number of individuals have been affected by the same illegal practice.
Our firm has extensive experience in handling antitrust cases and we would be honored to represent your interests in this matter. We believe that with our expertise and resources, we can successfully litigate this case and obtain the compensation that you deserve.
Please do not hesitate to contact us if you have any further questions or concerns. We look forward to the opportunity to work with you on this matter.
