Client Spotlight: Justin Weisweiller and "Ronald Mack Chaucer’s Gatwick Tales"
We at ABS&P International Law Firm, are proud to support creative minds in navigating the complexities of intellectual property law. One such success story comes from author Justin Weisweiller, whose innovative book, Ronald Mack Chaucer’s Gatwick Tales, reimagines Geoffrey Chaucer's classic Canterbury Tales in a modern airport setting. In this satirical epic, a group of delayed travelers at Gatwick Airport compete in a storytelling contest, blending iambic pentameter with wordplay, parodies, and hundreds of clever nods to literature, film, and culture.
Justin approached us for expert guidance on IP compliance, given the book's extensive references and homages. As he shared in his testimonial:
"Since the book includes parodies and contains hundreds of nods, homages and references to a wide range of other works, I needed clear advice on IP compliance. Plenty of books and online sources give bland generic advice on what variables affect compliance, but an author needs to know ‘Which side of the line does this specific reference fall?’ Only Dr Andre Alexander at ABS&P International Law Firm was able to give me clear and actionable answers so I could decide where to alter the text, where to add or extend attributions and where I could leave the text unchanged. I was very grateful for the speed, comprehensiveness, clarity and precision of the responses, and the willingness to clarify or expand on initial answers where necessary. Thanks to Dr Alexander’s clear, explanatory style, I was able to start learning for myself where the boundaries lie and increasingly answer my own remaining questions by extrapolating from answers I had already received. ‘Asking one question to answer ten’ contributed greatly to the cost-efficiency that a first-time self-publishing author needs."
Our assigned senior lawyer, Dr Andre Alexander, provided tailored, precise advice that empowered Justin to confidently self-publish while ensuring full compliance. This collaboration highlights our commitment to delivering efficient, client-focused IP solutions for artists and authors. You can purchase Ronald Mack Chaucer’s Gatwick Tales on Amazon UK and Amazon US.
Helping Children in Need
We are proud to support the Anak Terlantar Foundation, a small but deeply committed organisation working to transform the lives of children who have been orphaned, abandoned, or otherwise left without care. Since its establishment in 1995, the Foundation has offered safe havens and brighter futures to vulnerable children through direct support for projects, homes, and individual needs.
Through its Thrive Social Justice Fund, ABS&P contributes grants to Anak Terlantar and helps raise awareness of its vital work - particularly in Indonesia, where the Foundation currently supports medical initiatives and provides annual funding to the Eagle’s Nest Orphanage in Semarang. We are inspired by the Foundation’s hands-on approach and its unwavering commitment to dignity, care, and opportunity for every child it serves.
