You’re an engineer trying to work out a solution to a complicated problem. You have been at this problem for the last three days. You’ve been leveraging your expertise in innovative methods and other disciplined processes, but you still haven’t gotten to where you need to be.
Imagine if you could forego the last thirty hours of work, and instead you could have reached a novel solution in just 30 minutes. In addition to having saved yourself nearly a week of time, you would have not only arrived at a solution to your vexing engineering issue, but you also would have prepared all the necessary documentation to apply for intellectual property (IP) protection for it.
This is now what’s available from IP.com with its latest suite of workflow solutions dubbed IQ Ideas PlusTM. IQ Ideas Plus makes it easy for inventors to submit, refine, and collaborate on ideas that are then delivered to the IP team for review. This new workflow solution is built on IP.com’s AI natural language processing engine, Semantic GistTM, which the company has been refining since 1994. The IQ Ideas Plus portfolio was introduced earlier this year in the U.S. and has started rolling out worldwide.
“The great thing about Semantic Gist is that it is set up to do a true semantic search,” explained Dr. William Fowlkes, VP Analytics and Workflow Solutions at IP.com and developer of the IQ Ideas Plus solution. “It works off of your description. It does not require you to use arcane codes to define subject matters, to use keywords, or rely on complex Boolean constructs to find the key technology that you’re looking for.”
The program is leveraging AI to analyze your words. So, the description of your problem is turned into a query. The AI engine then analyzes that query for its technical content and then using essentially cosine-similarity-type techniques and vector math, it will search eight or nine million patents, from any field, that are similar to your problem.
“Even patents that look like they’re in a different field sometimes have some pieces, some key technology nuggets, that are actually similar to your problem and it will find those,” added Fowlkes.
In a typical session, you might spend 10 – 15 minutes describing your problem on the IQ Ideas Plus template, which includes root cause analysis, when you need to fix a specific problem, or system improvement analysis, when you are asked to develop the next big thing for an existing product. The template lists those elements that you need to include so that you describe all the relevant factors and how they work together.
The template involves a graphical user interface (GUI) that starts by asking you to name your new analysis and to describe the type of analysis you’ll be conducting: “Solve a Problem”, or “Improve a System”.
After you’ve chosen to ‘Solve a Problem’, for example, you are given a drop-down menu that asks you what field this problem resides in, i.e., mechanical engineering, electrical engineering, etc. The next drop-down menu then asks what sub-group this field belongs to, i.e., aerospace. After you’ve chosen your fields, you write a fairly simple description of your problem and ask for a solution (How do I fix…?).
You then press the button, and three to five seconds later, you’re provided two lists – “Functional Concepts” and “Inventive Principles”. One can think of the Functional Concepts list as a thorough catalogue of all the prior art in this area. What really distinguishes the IQ Ideas Plus process is the “Inventive Principles” list, which is abstractions from previous patents or patent applications.
The semantic engine returns ordered lists with the most relevant results at the top. Of course, as you scroll down through the list, after the first 10 to 20, the results become less and less relevant.
What will often happen is that as you work through both the “Functional Concepts” and “Inventive Principles” lists you begin to realize that you’ve omitted elements to your description, or that your description should go in a slightly different direction based on the results. While this represents a slightly iterative process, each iteration is just as fast as the first. In fact, it’s faster because you no longer need to spend 10 minutes writing down your changes. All along the process, there’s a workbook, similar to an electronic lab notebook, for you to jot down your ideas.
As you jot down your ideas based on the recommendations from the AI, it will offer you the ability to run a concept evaluation, telling you whether the concept is “marginally acceptable” or “good”, for example. You can use this concept evaluation tool to understand whether you have written your problem and solution in a way that it’s unique or novel, or whether you should consider going back to the drawing board to keep iterating on it.
When you get a high-scoring idea, the next module, called “Inventor’s Aide,” helps you write a very clear invention disclosure. In many organizations, drafting and submitting disclosures can be a pain point for engineers. Inventor’s Aide makes the process fast and easy providing suggestions to make the language clear and concise.
With the IQ Ideas Plus suite of tools, all of the paperwork (i.e., a list of related or similar patents, companies active in the field, a full technology landscape review, etc.) is included as attachments to your invention disclosure so that when it gets sent to the patent committee, they can look at the idea and know what art is already there and what technologies are in the space. They can then vet your idea, which has been delivered in a clear, concise manner with no jargon, so they understand the idea you have written.
The cycle time between a patent review committee looking at your disclosure and you getting it back can sometimes take weeks. IQ Ideas Plus shortens the cycle time, drives efficiencies and reduces a lot of frustration on both ends of the equation. Moving more complete disclosures through the system improves the grant rate of the applications because the tool has helped document necessary legwork during the process.
“IQ Ideas does a great job of both helping you to find novel solutions using the brainstorming modules, and then analyzing those new ideas using the Inventor’s Aide module,” Fowlkes said.
Fowkes argues that this really benefits both sides of the invention process – product development engineers and IP teams. For the engineers, filing invention disclosures is a very burdensome task. For the patent review committees or IP Counsel, getting clear, concise disclosures, free of jargon and acronyms and complete with documentation of prior art attached, makes the review faster and more efficient.
Professor Greg Gdowski, Executive Director of the Center for Medical Technology & Innovation, at the University of Rochester, deployed IQ Ideas Plus to his students earlier this year. According to Gdowski, IQ Ideas Plus is very valuable.
“We train our students in carrying out technology landscapes on unmet clinical needs that are observed in our surgical operating rooms. Despite our best efforts, the students always miss technologies that are out there in the form of patent or patent applications. IQ Ideas Plus not only helped us brainstorm additional solutions, but it also revealed existing technologies that would have complicated the solution space had they not been identified.”
Gdowski said another important advantage of using IQ Ideas Plus was that it helped the team understand the distribution of patents and companies working on technology related to a specific unmet clinical need (or problem). “IQ Ideas Plus gives engineers a new lens by which to evaluate solutions to problems and to execute intellectual property landscapes,” Gdowski added.
IQ Ideas Plus enables faster idea generation and collaboration, more complete documents for submission and review so the best ideas surface faster allowing great ideas to get to market faster.

inspectAR is an electronics productivity tool uniquely adapted to lab bench work. By separating a circuit board layout into an AR object consisting of nets and components, anyone who works on a circuit board physically can instantly connect to the expertise of the PCB designer.
Previously, while testing PCBs, you had to switch between circuit diagrams, pin assignments, data sheets and a prototype. Now, by clicking on a component you’re brought to its datasheet, supplier information, and a design-specific pinout. A complex net, such as ‘GND’ on a 12-layer board can be reduced to a set of probeable points, even if a test point was not configured in the design. In the case of fine-pitch components with a small distance between their pins, counting to the pin to-be-measured is error-prone. This first-in-market technology simplifies the analysis and repair of hardware products through augmented reality.
inspectAR overcomes the barrier of using software to interpret a design in the real-world by using a camera and image calibration to PCB manufacturing files (Only a mobile phone or external webcam is required).
Whether for tele-engineering, remote design collaboration, co-debugging, inner layer visualization, instant component lookup, net searching while in the lab, or easier-than-ever work instruction diagrams, inspectAR helps the modern hardware teams of today turn their PCB into a live and interactive, model-based piece of documentation once it comes back from the factory tomorrow.

The sailing speed record has been held for 8 years. A team of students and young engineers is in the process of developing a kiteboat to smash this record in 2022. Projected speed: 80 knots. The story of an audacious project told by two of its co-founders.
At 3:30 a.m. on Lake Geneva last July, under clear skies the air is fairly warm. Along the shoreline, you can see the lights of the town of Morges.
On board small boats, protected from indiscreet eyes in the half-light of dawn, a dozen young people are intently watching the behaviour of a 4-m long shape, pulled by a zodiac inflatable boat, cutting smoothly through the dark water. The technical problems revealed during the first test, five nights earlier, have been corrected. This time, the zodiac can accelerate, the shape follows it obediently. Data collected by the sensors confirm the impressions: everything goes according to the simulations.
This is excellent news for the three initiators of these night tests, Mayeul van den Broek, Xavier Lepercq and Benoît Gaudiot. Yet another step towards realizing their crazy dream – to beat the world sailing speed record. However, this will have to wait another two years if it all goes as planned. The sun is rising over the Mont-Blanc, unveiling its outline over the south shore of the lake: it is time to return the prototype discreetly into its shed.
Lepercq, van den Broek and Gaudiot were made to meet.
All three are French, sailing lovers and have decided to study engineering. Each of them has chosen the Federal Institute of Technology (EPFL), convinced by its naval competence. The prestigious institute had been a partner to the Swiss syndicate Alinghi (winners of the Americas Cup in 2003 and 2007) and of the “Hydroptère” the first large “flying boat” (sailing speed record in 2009).
Lepercq was already working and van den Broek finishing his Master’s degree in 2017, when they met Gaudiot, a first-year student. Their complicity was immediate. In the newcomer’s notebook, there were even sketches of kiteboats quite similar to theirs. Moreover, their interests were complimentary: engineering, materials, mechanical design, fluid dynamics … and Gaudiot, as an ex-member of the French national kitesurf team and Under-18 sailing speed record man, could be the ideal test pilot. When chances are all on your side to form a “dream team”, you must seize the opportunity. The three men thus decided to work together on a kiteboat project to make their speed world record dream come true. Their eyes riveted on the current record, set in November 2012 on Namibian waters by Paul Larsen. The Australian, at the helm of Vestas Sailrocket 2, beat two confirmed world records: on 500m at the speed of 65.45 knots (121.06kmph) and on the nautical mile (1852m) with 59.37 knots (109.94kmph). A real sporting feat, given that until then the 50-knot barrier seemed impassable for a vessel without an engine.
Just like the sound barrier, this limit is also dictated by the laws of physics. “At such speed, water pressure on the keel or the fin drops so rapidly that water starts boiling at ambient temperature.” explains Mayeul van den Broek. “This change increases drag and makes navigation very unstable – further acceleration becomes impossible.”
This phenomenon is called cavitation. Its powerful effects can blow into pieces the steel blades of a hydroelectric turbine. Their “scorch marks” can also be seen on the fins of tuna fish or dolphins, having paid painfully for their bold desire for speed.
“Paul Larsen used an innovative super-ventilating fin. This profile is used by hydroplanes, these engine-propelled boats flying at 350kmph, but was unprecedented in the world of sailing.” With its triangular shape and straight edges, this fin does not avoid cavitation, but manages to control the disturbing effect. “At high speed, the air bubbles remain stable”, explains Benoit Gaudiot, “there’s no more drag and so it is possible to continue accelerating.”
For the three friends, this is the key to Larsen’s record, rather than the asymmetrical design of Sailrocket 2 which had attracted full attention so far. They wanted to know for certain, so, in early 2018, they produce super-ventilating fins, in order to become familiar with the technology. They fitted them on a readily available support vessel that they knew well, a kitesurf. After three test runs on the Mediterranean, Gaudiot reached 41 knots (almost 80kmph). It is a proof of concept: combining a kitesurfing sail and a super-ventilating fin is the winning formula indeed.
However, 41 knots are not fast enough to benefit from the real potential of the super-ventilating fins: 50 knots should be the target speed. “We needed more power, so a larger kite” explains van den Broek. A kite that Gaudiot would not be able to hold with his arms. “This is when we came back to our idea of a boat.”
Between September 2018 and early 2019 the first concepts were drafted. Their sailing behaviour had to be simulated. As Velocity Prediction Programs (VPP) used by naval architects are too costly, LepercQ spent several months programming their own. As for van den Broek, with his Master’s degree in hand, he spends his time looking for sponsors and developing cooperation with the EPFL.
The VPP confirmed the design’s stability and the project’s feasibility. During the following months, the dream started taking shape. The EPFL recognized the project, gave access to its infrastructures and authorized students to participate in the project as part of their studies. In October, a student association was created, along with the SP80 company, the project owner. The project was officially launched and presented to the public. It was a success: the technical challenge was met, the exciting record-setting race and the spectacular kiteboat could be launched.
With its streamlined 7m hull, its closed cabin, its “wings” fitted with floats and a rear tailplane, the SP80 looks more like a jet than a boat.
Using composite materials, it weighs only 150kg when empty. At the end of a several-dozen-meter cable, a huge kite – sized between 20 to 50m2, depending on the needs. The power-to-weight ratio is absolutely amazing, “never reached before in the world of sailing!” highlights van den Broek.
It is so powerful, that the weight of the cabin does not even count in the equation. It doesn’t join the kite in the skies simply because its main hydrofoil is curved and “anchors” it into the water. These two opposing forces have also been used by Sailrocket 2. “This avoids capsizing: the stronger the kite pulls, the more the hydrofoil pulls to the opposite side.”
This permanent balance, created passively, is ensured by what SP80 calls the propulsion module. “It is the heart of the boat’s power, the place where all the forces are centred. The main idea of our design is to separate the rear module pushing the boat, from the cockpit that ensures the pilot’s stability and security.”
The design of the propulsion module, both mobile and robust, has taken up most part of the design phase. “We found solutions that were stable at certain speeds, but not at others. We had to find the best compromise.” The module being the key element of the boat, SP80 keeps these details confidential.
The design of the kiteboat completed, now it had to be tested in real conditions to prove the VPP simulations. A 1:2-scale prototype was designed and assembled by the students. It was this prototype that the SP80 team took for night testing in early July on Lake Geneva. About ten similar sessions have taken place until October.
Every night, several series of tests are run, returned on land in between, for adjustment and modification. The Zodiac pulls the prototype with a mast, simulating the kite and its cable. On the prototype, an inertial system records speed and acceleration and sensors follow the rotation speed, which is all you need to be able to verify the boat’s behaviour. The sensors are connected by robust IP68 LEMO connectors (K and E series) to the navigation system, collecting the data.
Early morning, the boat’s taken out of the water, dismounted and returned to the SP80 shed, the team analyses the videos and measurements. The aim is to make sure that no element of the boat is overcharged and no unnecessary force is generated. “For instance, that the immersed part of the rudder is not overloaded” explains Gaudiot, “since it is for the pilot to compensate, to be able to steer the boat.”
Lake Geneva does not offer optimal conditions (still waters, regular strong winds would be necessary to beat the record), but the tests are working out very well. As the design of the kiteboat is finally stabilised, SP80 has now started developing the ultimate boat.
The construction of the boat is scheduled to start early 2021, to be launched at the end of 2021. The world record attempt is planned for 2022.
By a strange coincidence, this agenda corresponds exactly to the plans of Syroco. Co-founded by French kitesurf star Alex Caizergues (the first to exceed 100kmph in sailing), this startup is also working on a kiteboat designed for beating the record and exceeding the 80 knots. However, competition does not intimidate SP80. “ On the contrary”, say Gaudiot and van den Broek. “Why not organise a shared event? It would be a spectacular “first!”
The SP80 Kiteboat
In view of the target speed, the boat’s design is inspired more by motor-boats than by sailing boats. It weighs more, using materials and structures to withstand higher loads. Sailing speed record regulations (drafted when the record stood at only 26 knots!) require human presence, but do not specify anything with regard to the pilot’s security. The SP80 pilot will be protected like off-shore pilots: closed cabin, six-point harness seat belt, oxygen mask in case of capsizing.
This is where the pilot is steering the boat and controls the kite. Since regulations forbid assisted steering, sensors and instruments only provide information to the pilot. They inform him for example if he must immediately drop the kite.
Always on the water, they ensure lateral stability and buffer the impact of waves. They slow down the boat a little bit, but are necessary for the pilot’s comfort.
- Main hydrofoil
Strongly curved, it “anchors” the boat into the water by opposing its force to the force of the kite, preventing the boat from lateral drag. Its profile is super-ventilated, limiting disturbance from cavitation and enabling the boat to exceed 50 knots.
The boat’s rudder is in an unusually forward position. It also has a super-ventilated profile to control the effects of cavitation.
- Power management module
This is where the flying kite’s cables are attached and that all forces are concentrated. The articulated system ensures passively the balance of forces between kite and fins, conferring power and preventing capsizing.
The prototypes are in the design process. As for kitesurf and paragliding, they should be made of fabric, possibly nylon. Among the available kites (between 20 and 50m2) the best adapted to wind conditions will be selected. This will also define the cable length (between 40 and 90m).

High Strength, Toughened Epoxy System Tested in Case Studies
Master Bond Supreme 10HT has demonstrated superior strength when used to bond surfaces under challenging conditions. It is a toughened system that is cryogenically serviceable from 4K to 400°F. It withstands mechanical and thermal shocks, meets NASA low outgassing specifications, and withstands 1,000 hours at 85°C/85% RH, with a Shore D hardness of 80. It has outstanding physical strength properties with tensile shear strengths exceeding 3,600 psi and T-peel strengths up to 30 pli. Because of its outstanding strength and other physical properties, Master Bond Supreme 10HT has been selected for use in several published research studies. Following are summaries of how Supreme 10HT performed in demanding applications outlined in these studies.
Adhesive for Electronic Control Components
The first case study involves an application for electronic control components, which perform logical and signal conditioning functions. A study conducted at L’École Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland, investigated alternative materials for use in high temperature control electronics packaging. Among the materials tested, were adhesives used for die-to-substrate assembly. Supreme 10HT was tested in this regard. Requirements for the die-to-substrate bond included reasonable bond strength and a suitable path for thermal dissipation. High temperature, and temperature cycling tests were conducted.
Adhesive for Capacitor Tank
The second case study involved an application for capacitor tanks. Capacitor tanks are commonly used in electrical power distribution systems to help maintain consistent line voltage levels. Because capacitor tanks– and in turn, the sealed joints between the capacitor bushings and metallic components– are commonly found at the top of utility poles and in electrical substations throughout the world, they are exposed to a myriad of environmental conditions Furthermore, these joints must be capable of maintaining such high performance over a period of approximately 30 years. Researchers at Cooper Technologies Company in Houston, Texas, ran performance tests on over a dozen commercially available epoxy resin products in an effort to identify compositions that may be used to seal capacitor tanks. Sup 10HT was one of over a dozen epoxies tested, and was one of four that exhibited sufficient strength for the application.
Yet another application involved an adhesive joint for a supersonic aircraft. Supersonic aircrafts are subjected to temperatures as low as -55°C when traveling at subsonic speeds at high altitudes and temperatures of approximately 200°C when traveling at or above Mach 2. A research team from the University of Porto (Portugal) and the University of Bristol (UK) set out to investigate the possibility of designing a mixed-adhesive joint consisting of both a low-temperature adhesive and a high-temperature adhesive that would support the required load across the entire temperature range. Master Bond Supreme 10HT was one of two low-temperature adhesives selected for the study. The researchers stipulated that the low-temperature adhesive should be ductile, stiff, and strong from -55°C to 100°C or higher in order to support the load throughout this temperature range. Additionally, the low-temperature adhesive should not degrade at temperatures above 100°C, where the high-temperature adhesive carries the load.
