It's World Intellectual Property Day on April 26 and this year celebrates the brilliance, ingenuity, curiosity and courage of the women who are driving change around the world and shaping our common future.

In that spirit, an invention by three Melbourne schoolgirls has the potential to solve a global problem on the world's tennis courts: keeping track of the score in social games.

Thirteen year-olds Alice Wilson, Susannah Lutze and Mikayla Lee, who are all in year 8 at Camberwell Girls Grammar School, have developed a simple device that straps to the throat of a tennis racquet that could resolve the constant question that bedevils amateur players everywhere: 'What's the score?'

The students, with the guidance of the Girls Invent program and pro bono work from intellectual property specialists at Spruson & Ferguson, are well advanced in securing IP protection over their invention, the Score Buddy, which has a potential global market.

Girls Invent runs specifically designed workshops to help guide girls to develop new products, from idea generation through to commercialisation and market entry. They currently operate programs in 150 Australian schools. CEO Mark Glazebrook said, "The Score Buddy team are a great example of the core ingredients for success: passion, determination, smarts and magnetism to bring people along with them. The Girls Invent program in partnership with the school creates the creative space for every girl to thrive and not just accept what others think they can do."

Spruson & Ferguson has supported Girls Invent through its pro bono program since 2016. Senior Associate Allira Hudson-Gofers (herself a mechatronics and biomedical engineer and an Australian representative player in handball and beach handball) said the girls' development work on Score Buddy was extremely impressive. A provisional patent application has been filed and discussions are underway about which other territories to file for IP protection. "All of the girls I've spoken with through the Girls Invent program are incredibly enthusiastic and have some great ideas. They've put together prototypes and thought ahead about the next steps in developing their inventions. It's really encouraging for these girls to be innovating and seeing the potential for STEAM subjects to lead to practical results and opportunities."

One of the Score Buddy inventors, Susannah Lutze, said, "We are really excited because we recently visited Tennis Australia's innovation centre and in a few weeks we are visiting an engineering company to possibly help us with the next stage."

The young inventors are seeking financial backers and, with help from a Dutch industrial design company, hope to have a working prototype completed by the end of the year.

Principal of Camberwell Girls Grammar School, Debbie Dunwoody, believes that an education focused firmly on the future is vital. "We want our students to develop entrepreneurial skills and we know that they will need to create their own opportunities in the future. Girls Invent is a really inspiring and accessible program for our girls to learn about and understand their capacity to be creative innovators. The program really connects them to all elements of STEAM (Science, Technology, Engineering, Arts, Mathematics) and focusses them on 'design thinking'.
